Magnesium alloy AZ63A reinforcement by alloying with gallium and using high-disperse ZrO_(2) particles

摘要

The aim of this work was to obtain an experimental magnesium alloy by remelting standard AZ63A alloy with addition of gallium ligatures and ZrO_(2) particles.This allowed reinforcement of alloy and increase its hardness and Young’s modulus.The chemical analysis of this alloy shows two types of structures which are evenly distributed in volume.Thus we can conclude that reinforcing effect is the result of formation of intermetallic phase Mg_(5)-Ga_(2).
