High-Temperature Deformation Mechanism in Composite Materials
Intermetallic compounds and ceramics such as oxides, carbides, nitrides, etc., are usually high in strength but brittle, whereas metals are in general ductile but low in strength. Many efforts are being made to produce composite materials having both high strength and ductility by combining them. Even in composite materials the strength decreases at high temperatures in many cases. The decrease is also caused by the increase in diffusion velocity. In this chapter will be described the kinds of materials which exist as useful composites and how their deformation is affected by diffusion.
