| Abstract | Effect of alloying elements on precipitation of delta phase in Ni-Nb-Cr-Mo alloys has been studied using thermodynamic method. It is found that an increase of Al/Ti ratio or (Al+Ti) content will inhibit the precipitation of delta phase obviously. When the Al/Ti ratio (exceed 1) or (Al+Ti) content increases, Nb content in delta phase increases, while the Mo content decreases. The mole fraction of delta phase increases obviously with increase of Nb content, however, it is nearly not affected by B content. Artificial neural network (ANN) method is tentatively applied to predict the multielement additions on mechanical properties in these alloys. A suitable composition of Al, Ti and B is suggested which obviously promotes stress-rupture life. The theoretical simulation results are finally verified through experiments.
