The effect of quenching rate on the temperature and strain-rate sensitivity of uranium 2w/o molybdenum alloy

The mechanical properties of a U2w/oMo alloy in the gamma-quenched, fast-gas-cooled and as-extruded states are compared at tensile strain rates from 0.0001 to approximately 2000/s. Significantly higher stress levels are observed in the gamma-quenched specimens at all strain rates and failure processes are studied by optical and scanning electron microscopy.
