Microstructure Modification of Magnesium Alloys by High Current Electropulsing

Article Preview

Abstract:

In this study, effects of high pulse current (current density :>103 A/cm2, applied time: 15 s) on microstructure of magnesium alloys were investigated. A mild steel was also employed as comparison material. Refinement of microstructure by electropulsing was observed in Mg-3B2O3 and mild steel and micro-Vickers hardness of these alloys were increased by modification of microstructure.
