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.
