Rejuvenation Heat Treatment of the Second-Generation Single-Crystal Superalloy DD6 [PDF]
Acta Metallurgica Sinica (English Letters), 2015 The second-generation single-crystal superalloy DD6 with [001] orientation was prepared by screw selecting method in the directionally solidified furnace. The long-term aging of the alloy after full heat treatment was performed at 1100 °C for 400 h. Then the rejuvenation heat treatment 1300 °C/4 h/AC + 1120 °C/4 h/AC + 870 °C/24 h/AC was carried out ...
