Effect of Warm Processing Parameters on the Precipitation of γ-phase in 2205 Duplez Stainless Steels

摘要：

Effect of the warm processing parameters (the strain rate, forming temperature and deformation degree) on the γ metastable phase transformation in 2205 duplex stainless steel has been studied. The γ metastable phase was located within the ferrite phase. Dynamic recovery took place only within the γ phase, and dynamic recrystallization underwent for the ferrite phase. The γmetastable phase transformation was affected by the deformation degree and about 15% deformation led to appearance of the γ metastable phase. γ metastable phase formation by the precipitation of intragranular γ was favored by increasing ageing time, and the size and content of γ metastable phase were related to deformation temperature and strain rates.
