Book Description
This book covers several aspects of the synthesis of composites by the pressureless infiltration technique. It describes the methods used to obtain green preforms, such as cold pressed and hot sintering, describing the heating time, load, and time required for pressing the preforms. Additionally, wettability phenomena, which is directly related on infiltration, is extensively described. Wettability process and interfacial reactions are analyzed in many ceramic-metal systems prior to fabricate the composites. A complete description of fabrication processes for Metal Matrix Composites is included. An extensive section on structural, chemical, and mechanical characterization of composites fabricated with aluminum and magnesium alloys as matrices reinforced with titanium carbide (TiC), aluminum nitride (AlN), silicon carbide (SiC) and alumina (Al2O3) is included. Relevant techniques for joining composites, such as welding and brazing are addressed. As well as issues pertaining to the corrosion and wear of composites are discussed as well. Corrosion behavior of some composites exposed to aqueous media was analyzed. Corrosion of composites using TiC and SiC like reinforcement and Al, Ni, and some Al-Cux, Al-Mgx and Al-Cu-Li alloys like matrix is discussed extensively. The structural characterization techniques addressed include: scanning electron microscopy (SEM), X-ray diffraction (XRD), transmission electron microscopy (TEM), optical microscopy (OM), differential thermal analysis (DTA), high resolution transmission electron microscopy (HRTEM), and thermogravimetry analysis (TGA). Mechanical testing including hardness, elastic modulus, tension tests, and impact tests were used in the characterization of composites. Theoretical models for prediction of some mechanical properties are included too.

Book Description
"It's about time that a practicing engineer with casting and academic experience has written a book that provides answers to questions about squeeze casting and semi-solid molding/forming that many engineers and students of casting need answered." —Joseph C. Benedyk, PhD, Consultant and retired technical director, Alcoa High Integrity Die Casting Processes provides a comprehensive look at the concepts behind advanced die casting technologies, including vacuum die casting, squeeze casting, and several variants of semi-solid metalworking. Practical applications for these processes are illustrated in numerous case studies. This single-source reference tool presents the latest material in five sections: Basic concepts of die casting and molten metal flow High integrity die casting processes with case studies Product design considerations Controlling quality and avoiding defects Future advances under development Key coverage includes a survey of liquid metal flow, strategies to overcome the limitations of conventional die casting, and potential defects unique to high integrity die casting processes. Also featured are methods for minimizing porosity, reducing cost by design, practical applied statistical process control techniques, designing for manufacturability, and containment methods for potential processing defects. Several chapters present detailed real-world examples illustrating the broad range of applications possible using high integrity die casting processes. Included with this book is a CD-ROM containing PowerPoint(r) presentations for each chapter. These presentations can be used for training purposes in conjunction with numerous study questions designed to practically apply the content of the book to real-world situations. Selected PowerPoint(r) slides can be used to support engineering proposals, marketing presentations, or customer education seminars. High Integrity Die Casting Processes is a valuable reference for both component producers and component users alike. Process engineers, tool designers, manufacturing engineers, production managers, and machine operators will acquire a better understanding of these advanced die casting processes to optimize manufacturing and improve product quality. Component designers, product engineers, purchasing agents, buyers, supplier quality engineers, and project managers will gain insight into these processes and develop superior products by design.

Book Description
Metal Matrix Composites (MMCs) are now attracting enormous interest, because of their superiority in strength, stiffness, wear resistance, elevated temperature strength or other engineering properties. Parallel to commercialisation, there are research centres throughout the world that are actively researching further development and exploitation of net or near net shape fabrication process. In this book, the production and characterisation of SiC particles reinforced Al alloy matrix composites produced by squeeze casting are investigated. The effects of volume fraction of SiC on microstructure, mechanical properties are examined as well. Also the results of the production of gravity cast matrix alloy, to determine the effect of pressure on microstructure and properties are described in this book.

Book Description
The premature failure in service of automobile components made up of aluminium and its alloys due to low mechanical strength, poor tribological behaviour, and poor thermal stability amounted to the emergence of composite materials, which exhibit better performance and could mitigate material failure in service. Aluminium based metal matrix composites were fabricated by two-step stir casting process using Si3N4 and ZrB2 as the reinforcing phases and AA8011 as the matrix phase. In this work, optical microscope (OPM), scanning electron microscope equipped with energy dispersive spectroscopy (SEM/EDS), and x-ray diffraction (XRD) were employed to examine the morphological evolution and the phases available in the developed composites. The hardness property, tensile strength, wear and friction response, and thermal behaviour were investigated using Vickers hardness tester, universal material testing (TQ SM 1000), universal tribometer (RTECH 2441), thermogravimetric analyzer (Perkin Elmer TGA 4000), and differential thermal analyzer (NETZSCH DTA 404) respectively. The corrosion performance of the developed composites was analyzed by linear polarization route in 0.5 M acidic environment (H2SO4). From the outcome of the experiments, the morphological appearance shows that the particulates were well dispersed in the AA8011 matrix, though sparingly distributed in composite with low percentage weight fraction of the particulates. The uniform dispersion of the particulates embedded in the matrix resulted to strong adhesion with negligible material defect between the two phases, and this was made possible by the process parameters employed during the two-step stir casting process. Generally, in all the developed composites viz: AA8011-xSi3N4, AA8011-xZrB2, and AA8011- Si3N4-ZrB2 composites (with the varying weight compositions of 0 wt.%, 5 wt.%, 10 wt.%, 15 wt.% and 20 wt.% of Si3N4, ZrB2, and Si3N4+ZrB2 particulates); composites with 20 wt.% fraction of the reinforcing Si3N4, ZrB2 and Si3N4+ZrB2 particulates possessed excellent properties in all the mechanical, corrosion and tribological evaluations carried out in comparison with the unreinforced AA8011. The melting temperature of the developed composites increases with an increase in the weight fraction of the particulates inclusion as revealed by DTA and affirmed by TGA for both the binary and the ternary composites. However, AA8011-20 wt.% ZrB2 possessed the best performing properties: highest hardness 63.84 HV and ultimate tensile strength 212.4 MPa, and the lowest wear rate 1.42 x 10-3 mm3/m with low coefficient of friction 0.117. Whereas, the hybrid composite of AA8011- 20wt.% Si3N4-ZrB2 had the lowest corrosion rate 0.9974 mm/yr, high melting temperature 676oC and the lowest weight loss 0.11 mg as a function of temperature.
