Evolution mechanism of recrystallization in a nickel-based single crystal superalloy under various cooling rates during heat treatment
文献摘要：
The recrystallization behaviors of a nickel-based single crystal superalloy during heat treatment at 1,200 ℃ for 4 h with various cooling rates were studied. Results show that the thickness of recrystallization layer decreases with the increase of cooling rate. In addition, the microstructures of γ' phase in the recrystallization region are different in various cooling rates. In the high cooling rates (70, 100 ℃·min-1), small size and high volume fraction of γ' phases are formed in the recrystallization region. It is also found that irregular fine secondary γ' phases are precipitated between matrix channels with an average size of 150 nm in the original matric (100 ℃·min-1). The sizes of the secondary γ' phase decrease with the increase of cooling rate. In contrast, large size and small volume fraction of γ' phases are formed in the recrystallization region, and a grain boundary layer is formed under a low cooling rate (10 ℃·min-1). The evolution mechanism of recrystallization at various cooling rates during heat treatment is analyzed.
