Deformation Behavior and Dynamic Recrystallization of Mg-1Li-1Al Alloy

In this paper, the hot workability of Mg-1Li-1Al (LA11) alloy is assessed through a uniaxial compression test in a temperature range from 200 to 400 °C and a strain rate, έ, of 1–0.01 s<sup>−1</sup>. The present study reveals that flow stress increases when the strain rate increases and...
