AbstractEffects of heat treatment on microstructure and mechanical property of a cast duplex stainless steel used as making impeller of seawater circular pump in nuclear power plant were investigated. The results demonstrate that the impact energy and elongation decrease sharply when heat-treated time was longer than 5 min at 800-850 degrees C or when the cooling rate was less than 7.5 degrees C/min. The a phases have been identified through SEM and XRD. The weakness of the mechanical properties is attributed to the precipitation of a phase. With increasing aging time, the a phase coarsened and the nucleation position moved from the gamma/delta interfaces into the whole ferrite phase.
