Abstract : Tensile testing of high volume fraction tungsten-aluminum and molybdenum-aluminum composites has been carried out at temperatures ranging from 25 to -196 C and elongation rates of 0.002 and 0.1 in./min respectively. The effect of constant strain rate tensile tests on observed fracture modes was investigated theoretically. Stress-strain behavior was analyzed by fiber size, inter-fiber spacing, character of flows, temperature, strain-rate and condition of material. (P.S.-PL)
