DYNAMIC RECRYSTALLIZATION OF MAGNESIUM AT AMBIENT-TEMPERATURE

This paper is concerned with structural changes taking place in pure m agnesium subjected to cold straining under heavy loading. It was shown that at T = 0.3 T(m) (melting point), low temperature dynamic recryst allization (LTDR) developed in the material. During LTDR, the size of dynamically recrystallized grains was found to be strain dependent. A certain relationship was established between this dependence and the d ominating deformation mechanisms. The causes of the strain dependence of the dynamic recrystallization parameters in magnesium are discussed .
