2914 メカニカルアロイングしたMg-Al合金粉末の型鍛造への応用(S34-2 粉末成形とその評価(2),S34 粉末成形とその評価)

抄録

Mechanically alloyed powder is active and has high driving force for sintering. The mechanical alloying (MA) of the mixture of AZ31 machined chip and the 40mol% and 61.5mol% aluminum powder was performed using high-energy ball mill. The mechanically alloyed powder was bonded on the surface of magnesium alloys (AZ31) by hot pressing and die forging at various temperatures and pressures. The bonded MA layer partially improved magnesium alloy surface by the die-forging.
