摘要：
Micro-alloying of Mg,ranged from 30 to 70 ppm,may improve the high temperatureductility,stress rupture,especially,certain important mechanical properties,such as cyclicstress rupture,creep/fatigue interaction and crack propagation rate.The quantity,morphology and distribution of δ-phase may obviously influence the notched cyclic stress rup-ture life.The relevant microstructure shows that the Mg may also influence to certain extenton the feature of δ-phase.Thus,to keep the Mg and δ-phase under control may further im-prove the mechanical properties of alloy GH169.
