Abstract
【解決手段】
本発明に係る金属部材は、金属の結晶粒(10)と、結晶粒の境界に形成されている粒状の強化物質(30)と、を備える。強化物質は、粒子面積相当粒径が結晶粒の粒子面積相当粒径の1/100より大きい形状を含む。粒状の強化物質(30)は、粒子面積相当粒径が前記結晶粒の粒子面積相当粒径の1/5より小さいものを含むことが望ましい。また、粒状の強化物質(30)は、長さが最も長い第1方向の長さを第1方向に直交する方向で最も長い部分の長さで割った値が5より小さい形状を含むことが望ましい。

Description
金属粉末射出成形で製造した金属が、鋳造、鍛造などで製造した金属に比べて高温での強度が低い原因を説明する。
以上の特性から、高温環境において強度の高い金属部材を金属粉末射出成形により形成する製造方法1を説明する。具体的には、製造方法1により、金属粉末射出成形を用いても、結晶粒の境界に強化物質が配置されている金属部材を製造する。
製造方法1で、ニッケル基合金の部材を製造した。具体的には、ニッケル基合金の粉末を用意した。このニッケル基合金の粉末は、最大粒径が20μmであり、炭素濃度は0.01質量%である。この炭素濃度は、製造後の金属部材の炭素濃度を約0.2質量%に制御するため、混合する強化用粉末の量に基づく値である。また、強化用粉末として、炭化チタンの粉末を用意した。この炭化チタンの粉末は、最大粒径が3μmである。混合した炭化チタンの量は、ニッケル基合金の粉末に対して、0.66質量%である。
