摘要	The influence of Co, W and Ti on stress-rupture lives of a Ni-Cr-Al-Mo-Ta-Co-W-Ti single crystal nickel-base superalloy has been investigated using a L-9 (3(4)) orthogonal array design (OAD) by statistical analysis. At a selected composition range, Ti content was the most important factor to the effect of the stress-rupture lives and then followed by Co content. W content had the minimum effect on stress-rupture lives. The optimal alloy should contain 10 wt pct Co, 8 wt pct W and zero Ti. The optimized alloy also had good microstructural stability during thermal exposure at 870 degrees C for 500 h.
