Abstract
The dynamic yield stress and the dynamic strength were measured for D16T aluminum alloy samples loaded by plane shock waves of submicrosecond duration. The temperature was varied from 20 to 470°C. It is established that the dynamic yield stress of the alloy decreases upon heating due to annealing. The dynamic yield stress of annealed samples increases with temperature, a fact that was observed earlier for aluminum. The dynamic strength of the alloy in the initial state decreases significantly upon heating, while the strength of the annealed material varies only slightly with temperature.
