Book Description
This technical memorandum describes an investigation of using friction stir welding (FSW) process for joining a variety of aluminum metal matrix composites (MMC's) reinforced with discontinuous silicon-carbide (SiC) particulate and functional gradient materials. Preliminary results show that FSW is feasible to weld aluminum MMC to MMC or to aluminum-lithium 2195 if the SiC reinforcement is less than 25 percent by volume fraction. However, a softening in the heat-affected zone was observed and is known to be one of the major limiting factors for joint strength. The pin tool's material is made from a low-cost steel tool H-13 material, and the pin tool's wear was excessive such that the pin tool length has to be manually adjusted for every 5 ft of weldment. Initially, boron-carbide coating was developed for pin tools, but it did not show asignificant improvement in wear resistance. Basically, FSW is applicable mainly for butt joining of flatplates. Therefore, FSW of cylindrical articles such as a flange to a duct with practical diameters ranging from 2-5 in. must be fully demonstrated and compared with other proven MMC joining techniques for cylindrical article

Book Description
Joining Processes for Dissimilar and Advanced Materials describes how to overcome the many challenges involved in the joining of similar and dissimilar materials resulting from factors including different thermal coefficients and melting points. Traditional joining processes are ineffective with many newly developed materials. The ever-increasing industrial demands for production efficiency and high-performance materials are also pushing this technology forward. The resulting emergence of advanced micro- and nanoscale material joining technologies, have provided many solutions to these challenges. Drawing on the latest research, this book describes primary and secondary processes for the joining of advanced materials such as metals and alloys, intermetallics, ceramics, glasses, polymers, superalloys, electronic materials and composites in similar and dissimilar combinations. It also covers details of joint design, quality assurance, economics and service life of the product. - Provides valuable information on innovative joining technologies including induction heating of metals, ultrasonic heating, and laser heating at micro- and nanoscale levels - Describes the newly developed modelling, simulation and digitalization of the joining process - Includes a methodology for characterization of joints

Book Description
Metal Matrix Composites by Friction Stir Processing discusses the capabilities of utilizing friction stir processing (FSP) as a tool to manufacture new materials, such as composites. FSP is considered a tool for grain refinement. However, this work illustrates how FSP has a wider capability due to the material flow and mixing the process offers. This book highlights such aspects by demonstrating the ability of the process to incorporate a second phase and make metal matrix composites (MMCs). The book covers the current research on processing MMCs by FSP, and presents a novel approach of making ductile MMCs by FSP using metal particle reinforcements. - Demonstrates how friction stir processing can be used to make metal matrix composites - Includes a review of different approaches of making metal matrix composites by friction stir processing - Demonstrates the utility of friction stir processing in making new types of non-equilibrium ductile composites - Provides a comparison of properties of friction stir processed composites to those of conventional metal matrix composites
