The dynamic yield strength and tensile (spall) strength of the D16T aluminum alloy are measured when samples are loaded by submicrosecond plane shock waves. The initial (unannealed) and annealed material is studied, and alloy samples subjected to multiple forging at elevated temperatures are also examined. The loading direction with respect to the texture of the material and the shock-compression pulse duration and shape are varied. The difference in the spall strengths measured along the rolling direction and normal to this direction is close to the dynamic yield strength of the material.
