Description
図1は、第1実施形態に係る焼結体製造システムの構成を示すブロック図である。第1実施形態に係る焼結体製造システム1は、TiAl系金属間化合物の焼結体の製造方法を実行するためのシステムである。TiAl系金属間化合物焼結体とは、TiAl系金属間化合物(TiAl系合金)を主成分とする焼結体である。本実施形態におけるTiAl系金属間化合物とは、Ti(チタン)とAl(アルミニウム)とが結合した化合物(TiAl、Ti3Al、Al3Ti等)である。ただし、TiAl系金属間化合物は、TiとAlとが結合している相であるTiAl相に、後述する混合金属Mを固溶するものであってもよい。
次に、第2実施形態について説明する。第2実施形態においては、添加金属として、Ni及びFe(鉄)を用いる点で、第1実施形態とは異なる。第2実施形態において、第1実施形態と構成が共通する箇所は、説明を省略する。
次に、第3実施形態について説明する。第3実施形態においては、TiAl系粉末体として、TiAl系金属間化合物の粉末であるTiAl系粉末と、添加金属としてNiを含有する添加金属粉末とを複数混合したものを用いる点で、第1実施形態とは異なる。第3実施形態において、第1実施形態と構成が共通する箇所は、説明を省略する。
次に、実施例について説明する。図5は、実施例と比較例との焼結密度を示す表である。図6及び図7は、比較例のTiAl系金属間化合物焼結体の金属組織の図である。図8及び図9は、実施例のTiAl系金属間化合物焼結体の金属組織の図である。図10は、Niの含有量と焼結密度との関係を示すグラフである。以下説明する各実施例では、金属粉末射出成型機で成形された成形体を脱脂後、焼結温度1450℃で2時間焼結して、TiAl系金属間化合物焼結体Fを製造した。以下説明する各比較例では、実施例と同様に金属粉末射出成型機で成形された成形体を脱脂後、焼結温度1450℃で2時間焼結して、TiAl系金属間化合物焼結体Fxを製造した。各実施例に係るTiAl系金属間化合物焼結体Fは、Alを30重量%、混合金属MとしてのNbを14重量%、混合金属MとしてのCrを0.7重量%含むものであり、各比較例に係るTiAl系金属間化合物焼結体Fxも同様である。
