Abstract
The mechanical properties of an ultra-high strength alloy steel for penetrator were studied under the strain rate range from 1600 to 1900 s -1 and temperatures range from room temperature to 500 K with a split Hopkinson tension bar, also, the tension fracture surface is examined by the SEM. The mechanical behaviors under high strain rate and high temperature were compared with that of 10 -3 s -1 strain rate and room temperature, the strength and fracture toughness of the alloy steel revealed strain rate and temperature relativities.
