- Abstract
The elastoplastic shock compression, unloading, and steplike shock compression of titanium at room temperature and in the vicinity of 600°C are measured. The dependences of the dynamic yield strength on the pressure of shock compression and temperature are determined, and the dependences of the strain rate in shock waves in the range 105–107 s–1 on the shear stress and temperature are obtained. In contrast to the data obtained for fcc metals, the yield strength of titanium behind a shock wave is found to decrease. The decrease in the yield strength is thought to be caused by a decrease in the plastic flow stress during the growth of twins and their reversibility.
