Plastic Deformation at High Temperature and Processing Map of AZ61 Magnesium Alloy

Abstract:

The deformation behavior of as-cast AZ61 alloy in the temperature range 300-450°C and in the strain rate range 0.01~5 s⁻¹ has been studied using processing maps. For obtaining the processing map, the variation of the efficiency of power dissipation given by [2m/(m+1)] where ‘m’ is the strain rate sensitivity, is plotted as a function of temperature and strain rate. The map exhibited a domain of dynamic recrystallization (DRX) occurring at 425 °C and 0.1 s⁻¹ which are the optimum parameters for hot working of the alloy.
