Abstract

Abstract

Chemical composition of gamma prime phase of alloy, the density of gamma, gamma prime and of alloy have been calculated with some formulae in references. The results of calculation agree with the measured results. span style="text-decoration:overline">NV and N_V^C in GH220 alloy with different content of W, Mo, Al, Ti and V are calculated too. There is not needlelike Mu phase if span style="text-decoration:overline">NV≤2.30.
