“…2. As usual, at a given strain rate, by increasing the strain we have seen that the flow stress firstly increases up to a maximum and then decreases to a steady state. The flow softening beyond the peak stress is attributed to DRX as well as coarsening of ␤ precipitates [8][9][10]. As expected, peak stress increases with strain rate and decreases with deformation temperature.…”

“…The value of Q obtained from Fig. 6(b) was 75 kJ/mol, which is significantly lower than those previously reported for the hot compression of bulk AZ91 Mg alloy [9,27]. This can primarily be attributed to the presence of pores in the structure of AZ91 powder compacts.…”

“…In the previous studies on hot deformation behavior of bulk AZ91 Mg alloy, the alloy was solutionized prior to hot compression [9,27]. Then, the alloying elements present in the chemical composition of AZ91 alloy, namely Al and Zn, can rationally be treated as mostly dissolved in the α-Mg solid solution phase.…”
