Abstract
An A7075 alloy was processed by high-pressure torsion (HPT) under an applied pressure of 6 GPa for 1, 3 and 5 revolutions with a rotation speed of 1 rpm at room temperature. Vickers microhardness saturated to a level of 220 Hv after the HPT processing and the grain size was refined to 3 120 nm at the state of the hardness saturation. Tensile tests were conducted with initial strain rates from 2.0
