Abstract

Magnesium alloys are used predominantly for high-pressure die-cast applications in which the use of a deliberate heat treatment is uncommon. This article provides information on the heat treatment designations for magnesium alloys. It describes the effects of grain size on magnesium alloys and the relationship between hardness and mechanical properties of the alloys. The article discusses the effects of elements such as aluminum, zinc, manganese, rare earths, and yttrium, on precipitation hardening. It describes the types of heat treatment for magnesium alloys, including annealing, stress relieving, solution treating and aging, and reheat treating. The article also discusses the preventive measures for the common problems encountered in heat treating magnesium alloys; and the evaluation of the effectiveness of heat treating procedures. In addition, it presents the processing steps involved in the heat treatment of magnesium alloys and in the prevention and control of magnesium fires.
