摘要: A combination of Gleeble thermo-mechanical physical simulation and analytical electron microscopy techniques was used to study non-equilibrium dissolution mode an equilibrium phase, δ phase precipitates, during rapid heating in IN 718 superalloy. In contrast the generally reported complete solid-state dissolution, result revealed that precipitates dissolved by liquation reaction, which is pertinent weldability hot formability behavior Nb-bearing nickel-based superalloys.
