[221] Fabrication of particle-dispersed nanocomposite and supersaturated solid solution by mechanical alloying of Al and Y2O3 powders

*Tatsuaki SAKAMOTO1, Yusuke JINNO2, Hiromichi TAKEBE1 (1. Graduate School of Ehime Univ., 2. Faculty of Engineering of Ehime Univ.)

Keywords:メカニカルアロイング、酸化物分散合金、Al合金、強制固溶、析出

AlとY2O3をメカニカルアロイングする際の雰囲気中の酸素濃度の違いにより、Al中にY2O3が析出した粒子分散粉末と、Al中にYとOが過飽和に固溶した過飽和固溶体粉末が作製された。
