Abstract

Equilibrium phases in alloy A286 and the influence of element contents on gamma prime (γ′) and carbides were studied by Thermo-Calc calculation. The phase equilibria, solidification behavior, and precipitation behavior of equilibrium phases were investigated. In the results, Al is considered as the critical element for γ′ phase control, and C is the vital element for the regulation of MC and M₂₃C₆ phases. The influence extents of different elements on the transition temperature and the maximum content of γ′ phase, MC phases, and M₂₃C₆ phases are determined in order as Al>Ti>Cr>Mo, C>Ti>Ni>Cr>Mo, and C>Ni>Cr>Mo, respectively. © 2018 Walter de Gruyter GmbH, Berlin/Boston.
