摘要
研究了Mar-M247合金双性能整体叶盘的热处理工艺,具体为:1180℃×2h+1230℃×3h空冷+1100℃×4h空冷+870℃×20h空冷。
The heat treatment conditions were investigated for double-properties cast integral turbine wheels of Mar-M247 Alloy. The heat treatment condition of Mar-M247 Alloy were obtained for 1180℃×2h+1230℃×3h,AC+ 1100℃×4h, AC+870℃×20h,AC.
