Using High-Pressure Torsion to Achieve Superplasticity in an AZ91 Magnesium Alloy
An AZ91 magnesium alloy (Mg-9%, Al-1% Zn) was processed by high-pressure torsion (HPT) after solution-heat treatment. Tensile tests were carried out at 423, 523, and 623 K in the strain rate range of 10<sup>−5</sup>−10<sup>−1</sup> s<sup>−1</sup> to evaluate the o...
