Research Abstract

平成4年度に発足した重点領域研究「新高温構造材料としての金属間化合物」の成果のとりまとめを行った。初年度から3年間にわたる研究によって、Ti-Al系、Ni-Al系、Nb-Al系金属間化合物の変形機構と組織の微視的理解に関して注目すべき成果が得られた。特に、新しい軽量高温材料として注目されているTiAl/Ti_3Al系金属間化合物の力学特性について、国際的に注目される成果が得られている。これらの成果は膨大な数の論文としてすでに発表または発表準備中であるが、これらの論文リストと領域の4分野「結晶構造の予測と制御」、「変形と破壊のメカニズム」、「組織設計と制御」、「耐環境性」における成果の概要を含む報告書、ならびに本領域の最新の研究成果を集大成するため、金属間化合物研究における国際専門誌であるIntermetallicsの特集号を刊行した。
