摘要：

The effect of cornpression on the rnicrostructures and flow behavior of WE43 magnesium alloy was investigated in this article. The relationship between flow stress and strain rate was discussed. According to the empirical formula i = Aor" exp(-QIRT), the value of heat activation of WE43 rnagnesiurn alloys is 297.15 U/mol. A mechanism of deformation softening of WF-43 alloy in testing hot deformation was identified to be dynamic recrystallization.
