Abstract
With an increasing demand for light-weight materials to reduce the fuel consumption especially in transportation industry, researches on magnesium alloys have been extensively conducted. The intrinsic poor formability and ductility at ambient temperature due to the hexagonal close-packed (HCP) crystal structure and the associated insufficient independent slip systems restricts their practical usage. Hot working of magnesium alloys during a forging and extrusion process enables net-shape manufacturing with enhanced formability and ductility since there are several non-basal slip systems operated in addition to the basal slip plane leading to increase of the plastic workability. In this research, thermomechanical properties of AZ80 Mg alloy are obtained through conducting compression tests under various temperatures and strain rates in which microstructural behaviors such as texture evolution and dynamic recrystallization are investigated to correlate it with hardening, softening behavior, and material anisotropy of Mg alloys using EBSD experiment. Experimental data with physical explanations suggest optimal forming conditions for net-shape forging under hot or warm temperature by controlling the grain refinement and working conditions.
