Effect of Slow Cooling Treatment on Microstructure and Dynamic Recrystallizaiton of FGH96 Alloy

Abstract:

The effect of slow cooling treatment (SCT) on the microstructure and dynamic recrystallization of FGH96 alloy was studied. The results show that the grains of FGH96 alloy after slow cooling rate treatment grow from 20μm~30μm to 30μm~40μm, and the distance between γ′ precipitates in FGH96 alloy becomes larger. This promotes the dynamic recrystallization in the process of hot extrusion and isothermal hot compression and decreases the flow stress effectively.
