The method of enhancement of workability in AZ31 alloy, a commonly used magnesium alloy is discussed. The capability of the material to be processed under plastic deformation without fracturing is known as workability. It is the material property that can be influenced by several factors as initial microstructure, temperature and strain rate applied, and stress state in the deformation zone. The technique of processing maps based on the Dynamic Material Model (DMM) is beneficial for optimizing the workability and controlling the structural development during processing. The processing maps are constructed by superimposition of two independent maps, a power dissipation map which represents in a frame of temperature and strain rates, in which material dissipates the power through the microstructural changes. Processing maps were generated over a wide range of temperatures and strain rates and two microstructural domains were delineated.
