具有优良的不易产生偏析的性能的Ni基高温合金
Abstract:
本发明的目的是在制造包含Ni基高温合金的材料时，减少条纹型偏析的发生。本发明涉及一种具有优良的不易产生偏析的性能的Ni基高温合金，其特征在于，包含：0.005～0.15质量％的C、8～22质量％的Cr、5～30质量％的Co、等于或大于1质量％且小于9质量％的Mo、5～21质量％的W、0.1～2.0质量％的Al、0.3～2.5质量％的Ti、最高0.015质量％的B和最高0.01质量％的Mg，其余包含Ni和不可避免的杂质。
Abstract(English):

The invention aims to reduce streak-like segregation in producing a material of an Ni-base superalloy. The invention relates to an Ni-base superalloy with excellent segregation properties, characterized by containing by mass C: 0.005 to 0.15%, Cr: 8 to 22%, Co: 5 to 30%, Mo: 1% to less than 9%, W: 5 to 21%, Al: 0.1 to 2.0%, Ti: 0.3 to 2.5%, B: 0.015% or less, and Mg: 0.01% or less with the balance being Ni and unavoidable impurities.
