The quantity,morphology and distribution of δ-phase may obviously influence the notched cyclic stressrupture life. The relevant microstructure shows that the Mg may also influence to a certain ex-tent on the feature of δ-phase. Thus, keeping the Mg and δ-phase under control may furtherimprove the mechanical properties of GH169 alloy.
