摘要：
The second phase precipitation strengthening effect of gamma ', gamma '+gamma ', gamma '+gamma ' phases in INCONEL718 type and newly developed INCONEL740 (R) Ni-base superalloys and their structure stability have been studied Experimental results show that careful control of Nb, Ti and Al for alloy modification can not only raise their strengths but also improve structure stability at high temperatures. These modified newly developed alloys are suggested to be used at higher temperatures
