Metal Matrix Composites Processing And Interfaces

Metal Matrix Composites: Processing and Interfaces provides a unified source of information on metal matrix composites (MMCs). This book contains three parts. Part 1 provides the introductory overview, focusing on the historical perspective on the state of the composites field. The synthesis and processing details on some standard and novel techniques used to fabricate composites are discussed in Part 2. Part 3 is devoted to reviewing techniques in probing, modeling, and modifying composite interfaces. Other topics include the diffusion brazing techniques, chemical vapor deposition, and in situ reinforcement of MMCs. The deformation processing of metal mixtures and optimizing properties of deformation-processed metal/metal composites are also covered in this text. This publication is useful to engineering students studying the processing and interfaces of MMCs.

Interfaces in Metal Matrix Composites, Volume 1 presents the position of the science of interfaces, as well as the necessary background for the effort in progress to apply these materials. The book discusses the mechanical and physical aspects of the interface; the effect of the interface on longitudinal tensile properties; and the effect of the filament-matrix interface on off-axis tensile strength. The text also describes the role of the interface on elastic-plastic composite behavior; the effect of interface on fracture; and the interfaces in oxide reinforced metals and in directionally solidified eutectics. The effect of impurity on reinforcement-matrix compatibility is also considered. Metallurgical engineers and people involved in the study of materials science will find the book invaluable.

`Metal-Matrix Composites' are being used or considered for use in a variety of applications in the automotive, aerospace and sporting goods industries. This book contains sixteen chapters, all written by leading experts in the filed, which focus on the processing, microstructure and characterization, mechanics and micromechanics of deformation, mechanics and micromechanics of damage and fracture, and practical applications of a wide variety of metal composites. A particularly noteworthy feature of this authoritative volume is its collection of state-of-the-art reviews of the relationships among processing, microstructural evolution, micromechanics of deformation and overall mechanical response.

The issues in this research focused on the understanding the chemical evolution (diffusional) process at the interface, developing a mechanistic model or an interface based on stress or energy failure criterion, and studying the effect of interface properties on the performance of the composites. The approach involved both experimental and computational components, a link between the evolution of chemistry and geometry of the reaction zone and the interfacial properties. Microstructural studies reveal that reaction growth is due to transformation of both coating and the matrix. Push-out tests conducted on heat treated specimens reveal that the effect of thermal exposure on interfacial properties is predominantly due to exposure temperature. Time of exposure is found to have only a secondary effect. The push out data was used indirectly to evaluate both strength and toughness properties of the interfaces. The local shear strength of Ti-6A14V/SCS-6 interfaces was found to be of the order og 450 Mpa, in comparison with much lower (120 Mpa) average shear strength reported elsewhere. Also a fracture toughness of 50 Mpa m 1/2 was found in this research . Also the fracture toughness values remain more or less constant for normal use temperatures in the range of 450 to 700 deg C.

This book the current status of metal matrix covers composites which are produced via solidification technology. It examines processes involved in the synthesizing of composites, structure/property relationships, and established and emerging industrial applications, particularly in the automotive industry.

Metal matrix composites are making tangible inroads into the "real" world of engineering. They are used in engineering components such as brake rotors, aircraft parts, combustion engines, and heat sinks for electronic systems. Yet, outside a relatively limited circle of specialists, these materials are mostly unknown. Designers do not as a rule think of using these materials, in part because access to information is difficult as these materials have not really entered engineering handbooks. Metal Matrix Composites in Industry is thus useful to engineers who wish to gain introductory knowledge of these materials and who want to know where "to find" them. Additionally, it provides researchers and academics with a survey of current industrial activity in this area of technology.
