NiAl/TiB{sub 2} functionally graded composites were produced by the combustion synthesis process. X-ray diffraction and optical microscopy were used to characterize the microstructure. Hardness measurement at room temperature and 900{degrees}C were used to probe the mechanical properties. The Vickers hardness at room temperature varies linearly with TiB{sub 2} content. However, the high temperature hardness varies non-linearly with TiB{sub 2} content and is sensitive to microstructure. In particular, plastic flow in NiAl at high temperature depends on TiB{sub 2} particle size.
