Abstract

The effects of elevated temperature at high strain rate of a commercial tungsten alloy were investigated. The tests were carried-out at high strainrate (from 850 to 2200 1/s) by means of a Split Hopkinson Tension Bar device on round specimens having diameter and gauge length of 2mm and 5 mm, respectively. The thermal conditions were obtained by means of a water-cooled induction heating system on the specimen mounted on the SHTB. The dependence of ultimate tensile strength on temperature was found to decrease, while the failure strain increased with temperature. The strain rate linearly growths with the temperature.
