This paper is concerned with structural changes taking place in pure magnesium subjected to cold straining under heavy loading. It was shown that at T = 0.3 T[sub m] (melting point), low temperature dynamic recrystallization (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 dominating deformation mechanisms. The causes of the strain dependence of the dynamic recrystallization parameters in magnesium are discussed. (orig.)
