Summary

The microstructure of cast magnesium-zinc-aluminum based alloys can be modified by heat treatment and their mechanical properties can be improved at room temperature as well as elevated temperature. In this study, specific heat treatments have been performed on ZA104 and ZA10403 (0,3%Ca) alloys in order to precipitate intermetallic phases in the matrix and determine their effects on mechanical properties. The hardness, tensile strength, ductility, and creep resistance of these alloys has been determined as a function of temperature and duration of heat treatment. The evolution of microstructure with heat treatment is reported and discussed in order to explain the changes in mechanical behaviour.
