摘要

Effects of Mo and W on creep strength of low Cr heat resistant steels have been investigated from the stand points of the phase stability of precipitates during long-term exposure at the elevated temperatures. The study on 2.25/100Cr-Mo-V-Nb (Mo-steel) and 2.25/100Cr-W-V-Nb (W-steel) with a same amount of Mo- Equivalent has shown that the substituting W for Mo retards the evolution of microstructure. And thus re- Markably improves the creep rupture strength.
