Book Description
The objective of this study is to significantly advance the fundamental knowledge to enable scalable nano-manufacturing of metal-based nanocomposites by overcoming the grand challenges that exist in both fundamental and manufacturing levels. It especially seeks to manufacture bulk aluminum nanocomposite electrical conductors (ANECs) with uniform dispersion and distribution of nanoparticles that offer excellent mechanical and electrical properties. Polymer-metal nanocomposite is an emerging class of hybrid materials which can offer significantly improved functional properties (e.g. electrical conductivity). Incorporating proper nanoscale metallic elements into polymer matrices can enhance the electrical conductivity of the polymers. To achieve such polymer nanocomposites, the longstanding challenge of uniform dispersion of metal nanoparticles in polymers must be addressed. Conventional scale-down techniques often are only able to shrink larger elements (e.g. microparticles and microfibers) into micro/nano-elements (i.e. nanoparticles and nanofibers) without significant modification in their relative spatial and size distributions. This study uncovers an unusual phenomenon that tin (Sn) microparticles with both poor size distribution and spatial dispersion were stretched into uniformly dispersed and sized nanoparticles in polyethersulfone (PES) using thermal drawing method. It is believed that the capillary instability plays a crucial role during thermal drawing. This novel, inexpensive, and scalable method overcomes the longstanding challenge to produce bulk polymer-metal nanocomposites (PMNCs) with a uniform dispersion of metallic nano-elements (Chapter 3). Nano-elements (e.g. nanoparticles) are one of the most important constituent of the nanocomposite materials. Since titanium diboride (TiB2) nanoparticles is of a crucial factor in this study, and more importantly is not commercially available, we synthesized these reinforcements to ensure high purity and size uniformity. Our preliminary results show that TiB2 nanoparticles with a uniform size can be produced. Further characterization confirmed the presence of crystalline TiB2 nanoparticles with average size of 8.1i 0.4 nm. The in-house synthesized TiB2 nanoparticles were used to reinforce both aluminum and magnesium matrices. Successful incorporation of TiB2 nanoparticles in the aforementioned matrices was another indirection indication of high purity and surface-clean TiB2 nanoparticles (Chapter 4). Lightweight metallic systems (e.g. Al) have promising potentials for applications in metal-based laser additive manufacturing. Lightweight metals exhibit moderate mechanical properties compare to high density metals (e.g. steel). However, lightweight metal matrix nanocomposites (LMMNCs) offer excellent mechanical properties desirable to improve energy efficiency and system performance for widespread applications including, but not limited to, aerospace, transportation, electronics, automotive, and defense. It has been a longstanding challenge to realize a scalable manufacturing method to produce metal nanocomposite microparticles. This study demonstrates high volume manufacturing of Al and magnesiuim (Mg) nanocomposite microparticles. In-house synthesized TiB2 and commercial titanium carbide (TiC) nanoparticles were chosen as nano-scale reinforcements. Using a flux-assisted solidification processing method, up to 30% volume fraction nanoparticles were efficiently incorporated and dispersed into Al and Mg microparticles. Theoretical study on nanoparticle interactions in molten metals revealed that TiC and TiB2 nanoparticles can be self-dispersed and self-stabilized in molten Al and Mg matrices. Metal-based additive manufacturing and thermal spraying coating can significantly benefit from these novel Al and Mg nanocomposite microparticles. This simple yet scalable approach can broaden the applications of such nanocomposite in additive manufacturing of the functional parts. Moreover, the metal nanocomposite microparticles can be applied in conventional manufacturing processing. For example, bulk Al-30 volume percent (vol. %) nanocomposites were produced by cold compaction of Al-30 vol. % TiB2 nanocomposite microparticles followed by melting. Al-30 vol. % TiB2 nanocomposites with average Vickers hardness of 458 HV was successfully produced (Chapter 5). Magnesium is the lightest structure metal applied in broad range of applications in various industries such as biomedical, transportation, construction, naval and electronic. Strengthening Mg is of significance for energy efficiency of numerous transportation systems. Traditional metal strengthening approaches such as elemental alloying have reached their fundamental limits in offering high strength metals functioning at elevated temperature. Adding nanoparticle reinforcements can effectively promote the mechanical properties of Mg nanocomposites. However, manufacturing of bulk magnesium nanocomposites with populous and dispersed nanoparticles remains as a great challenge. Here we report a novel flux-assisted liquid state processing of bulk Mg nanocomposites with TiC as the nanoscale reinforcements. TiC nanoparticles with high hardness and high elastic modulus is well-distributed and uniformly dispersed in the Mg matrix, resulting in a significantly improved Vickers hardness of 143.5i 11.5 HV (pure Mg Vickers hardness is about 35 HV). Further theoretical study suggested that TiC nanoparticles can be self-dispersed and self-stabilized in Mg matrix (Chapter 6). Aluminum is one of the most abundant lightweight metal on Earth with a wide range of practical applications such as electrical wire. However, traditional aluminum manufacturing processing approaches such as elemental alloying, deformation and thermomechanical cannot offer further property improvement due to fundamental limitations. Successful incorporation of ceramic nanoparticles into aluminum have shown unusual property improvements. Adding metal-like ceramic nanoparticles into aluminum matrix can be a promising alternative to produce high performance aluminum electrical wires. Here we show a new class of aluminum nanocomposite electrical conductors (ANECs), with significantly improved average Vickers hardness (130 HV) and good electrical conductivity (41% IACS). The as-cast Al-3 vol. % TiB2 nanocomposites exhibit yield strength of 206.6 MPa, UTS of 219.6 MPa, tensile strain of 4.3% and electrical conductivity of 57.5% IACS (pure Al has yield strength of 35 MPa, UTS of 90 MPa, tensile strain of 12% and electrical conductivity of 62.5% IACS). We also observed an unusual ultra-fine grain (UFG) size, as small as 300 nm, in the ANEC samples under slow cooling. We believe that the significant mechanical property enhancements can be partially attributed to the existence of the UFG. Further investigations demonstrated that UFG can be achieved when nanoparticles are uniformly dispersed and distributed in the aluminum matrix (Chapter 7). In summary, analytical, numerical and experimental approaches have been established to significantly advance fundamental understanding of polymeric and metallic matrix nanocomposites, in particular the effect of metal-like ceramics on mechanical and electrical properties of lightweight metals. This study has demonstrated scalable production of multi-functional metal and polymer matrix nanocomposites. Metal-like ceramic nanoparticles can significantly enhance the mechanical properties of metal matrix while retaining good electrical properties.

Book Description
The objective of this study is to experimentally provide insights and guidance for rational design of laser additively manufactured high-performance metal matrix nanocomposites (MMNCs) for various applications. Laser additive manufacturing (LAM) has emerged as a popular metal manufacturing platform to accelerate novel material creation and build high performance products with complex geometries that traditional processes have been impossible to fabricate. However, there still exist great challenges in LAM of conventional metals and its alloys such as absence of porosities, poor surface morphologies or hot cracking, deteriorating the resulting material performance. MMNCs consisting two or more different phases give a potential opportunity to obtain enhanced material properties, suggesting a novel route for LAM to tackle the great challenges. Nevertheless, problems arise from agglomeration of nanoparticles and processing difficulties due to the introduction of secondary phase. In this dissertation, a wide variety of MMNCs were laser additively manufactured to experimentally study the nanoparticle effects on powder morphology, laser reflectivity, micro/nanostructure and resulting material performance, providing insightful processing routines for LAM of high-performance MMNCs. The MMNC powder is one of the major factors for LAM to obtain a desired component. In this study, two fabrication techniques, i.e., nanoparticle self-assembly with assistance of ultrasonic processing or mechanical mixing, were used to produce MMNC powders including aluminum metal matrix nanocomposites (AMNCs), aluminum silicon alloy matrix nanocomposites (AlSi12-TiC), and copper matrix nanocomposites (Cu-WC). MMNC powders with different volume ratio (x) between nanoparticles, i.e., titanium carbide (TiC) or tungsten carbide (WC), and matrix, i.e., Al, AlSi12 or Cu, were prepared, including AMNC with x=0.25 and x=1, AlSi12-TiC with x=0.05; x=0.25, and Cu-WC with x=0.1, x=0.25; x=0.66, respectively. The reflectivity measurements of ultrasonic processed powders show a significant decrease in laser reflectivity at the wavelength of 1070 nm as the nanoparticle fraction increases. Moreover, the analysis of light scattering (LS) and scanning electron microscope (SEM) reveals that a uniform size distribution of ultrasonic processed powders. Nanoparticles were self-assembled at the surface of the matrix powders due to the favorable energy state. Internal microstructures revealed by focused ion beam (FIB) show a uniform distribution and good dispersion of nanoparticles throughout the matrix powders. In addition, to demonstrate the scalability, two different mechanical mixing techniques were developed to produce MMNC powders, namely, wet mechanical mixing and dry mechanical mixing. Whereas the powders produced via wet mechanical mixing show the laser reflectivity of the powders decreases as the nanoparticle fraction increases, while the reflectivity of dry mechanical mixed powder, i.e., Cu-WC (x=0.66), only exhibits a slight reduction due to the less nanoparticle coverage on the matrix copper. The powders (Al system) with a spherical shape and uniform size produced by wet mechanical mixing are similar to those by the ultrasonic processing, demonstrating a good scalability of the technique. For copper matrix system, more efforts are still needed to improve the powder morphology, size distribution, and nanoparticle dispersion and distribution inside the matrix. This study provides a scalable and low cost route for mass production of MMNC powders with high loadings of nanoparticle for LAM. Experimental studies on LAM of two types of AMNC powders were carried out to investigate the nanoparticle effects on micro/nanostructure and material performance. Assembled powders by both ultrasonic processing and mechanical mixing, were additively manufactured by laser melting using a customized laser additive manufacturing system. AMNCs (with 17 vol.% TiC and 35 vol.% TiC) were successfully laser deposited via laser melting. The material performance shows that the Young's modulus, yield strength, and hardness of the AMNCs increase as the nanoparticle fraction increases. The AMNC (35 vol.% TiC) delivers a yield strength of up to 1.0 GPa, plasticity over 10 %, and Young's modulus of approximately 200 GPa. The AMNC (35 vol.% TiC) offers unprecedented performance in terms of specific yield strength, specific Young's modulus, and elevated temperature stability at 400 i C amongst all aluminum alloys. The exceptional mechanical properties are attributed to high density of well-dispersed nanoparticles, strong interfacial bonding between nanoparticles to aluminum, and ultrafine grain sizes (approximately 331 nm). Additionally, AMNC (15 vol.% TiC) sample was laser deposited via melting of powders produced by the mechanical mixing, offering comparable mechanical properties to that of AMNC (17 vol.% TiC). The study paves a new pathway for laser additive manufacturing of nanoparticles reinforced aluminum for widespread applications. To achieve comparable mechanical properties of AMNCs, laser additive manufactured AlSi12 matrix nanocomposites, i.e., AlSi12-TiC (x=0.05 and x=0.25), were successfully produced. Micro/nanostructure analysis shows that the grain size of AlSi12-TiC nanocomposites decrease as the fraction of incorporated nanoparticles increases. Additionally, chemical reaction products, i.e., SiC nanoparticles and Al3Ti intermetallic phase, have been identified and observed by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The microhardness and Young's modulus of the laser deposited AlSi12-TiC (x=0.25) were increased to 578 i 42.5 HV and 187.73 i 28 GPa, respectively, showing comparable properties to that of AMNC (35 vol.% TiC), i.e., 330.3 i 30.6 HV and 197 i 27 GPa. The improved results can be attributed to the dispersed nanoparticles and reaction products. This research suggests a new design route to directly deposit high performance aluminum alloys by benefiting from the strengthening effects of the minor phase(s) in alloy while decreasing the amount of incorporated nanoparticles. The experiments on LAM of Cu matrix nanocomposites were carried out to explore the feasibility on high performance copper materials. While a great number of porosities with ball-liked morphologies appeared after laser melting of the powders on a pure copper substrate, good layer uniformity and densification of the additively manufactured samples were obtained by replacing the pure Cu with nickel or as-cast MMNC substrate, mainly because of less thermal conductivity difference and good wettability between the powders and substrates. The internal microstructures exhibit a uniform nanoparticle distribution but some nanoparticle agglomeration exists in the matrix. The grain structure of laser deposited samples has refined by the laser induced rapid solidification rate and incorporated nanoparticles, showing a smaller grain size than that of as-cast MMNC samples. The study experimentally demonstrates a feasible processing way to directly laser deposit dense Cu matrix nanocomposites. In summary, extensive experimental studies presented in this dissertation have demonstrated various feasible processing methods of LAM to produce high-performance MMNC. A wide variety of laser deposited MMNCs produced in this study can provide insights and guidance to LAM on powder fabrication (nanoparticle selection, volume fractions, reflectivity, size and morphology, and scalability) and processing/microstructure/properties relationships. This study also advances the knowledge base for rational design of high-performance MMNCs with desirable properties for various applications.
