| Abstract: | This paper analyzes the deformation behavior of the AZ31 magnesium alloy by isothermal compression in the range of temperature 473 K - 623 K at 0. 001 - 1s^ -1 strain rate. Dynamic recrystallization is a main mechanism responsible for grain refinement during the test conditions. This paper analyzes the changes of micro-mechanisms to study the mechanism of dynamic recrystallization and studies the effect of twinning crystallization on recrystaUization mechanisms. |

| Keywords: | magnesium alloy hot deformation dynamic recrystallization processing straining rate |
