Nickel base superalloy with improved machinability and method of making thereof

摘要：

Machineable nickel base alloy casting, consisting essentially of, in weight %, about 12.5% to 15% Cr, about 9.00% to 10.00% Co, about 3.70% to 4.30% Mo, about 3.70% to 4.30% W, about 2.80% to 3.20% Al, about 4.80% to 5.20% Ti, about 0.005% to 0.02% B, up to about 0.10% Zr, and balance essentially Ni and carbon below about 0.08 weight % to improve machinability while retaining alloy strength properties after appropriate heat treatment.

摘要（中）：

可机加工的镍基合金铸件，主要由重量％，约12.5％至15％的Cr，约9.00％至10.00％的Co，约3.70％至4.30％的Mo，约3.70％至4.30％的W，约2.80％ 3.20％Al，约4.80％至5.20％的Ti，约0.005％至0.02％的B，至多约0.10％的Zr，余量基本上为Ni和低于约0.08重量％的碳，以提高机械加工性，同时在合适的热处理后保持合金强度性能。
