The microstructural stability and mechanical behavior of the in-situ Co,Cr-Cr,Co7C3 composite and filamentary Ni-Mo and nichrome-tungsten composites have been characterized as a function of isothermal exposure and various regimes of thermal cycling. Properties examined were strength, toughness and resistance to fatigue crack propagation. Correlations were developed between microstructural change accompanying each mode of heat-treatment and the above properties. This provided the basis for the development of models for plastic flow and crack initiationpropagation in the two types of composite material which can account for the observed effects of the heat-treatment imposed.
