Evolution of γ' precipitates in GH4742 superalloy based on complete forging-heat treatment process
文献摘要：
The temperature changes at the rim,1/2 radius,and bore of the turbine disk during the solution treatment were measured.Based on the measured temperature data,solution treatment experiments with different cooling rates(14,51,and 93℃/min)were performed,and the solution temperatures were 1120 and 1080℃.At all three cooling rates,the multimodal size distribution of γ'precipitates was detected,and the size of γ'precipitates is inversely related to the cooling rate.Only the secondary and tertiary γ'precipitates were found at a solution temperature of 1120℃,and the secondary γ'precipitates progressed from spherical(93 and 51℃/min)to flower-like(14℃/min)shape,with the flower-like γ'precipitates regulated by aggregation.At a solution temperature of 1080℃,the γ'precipitates evolve from cuboids(93 and 51℃/min)to irregular shapes(14℃/min).Irregular γ'precipitates are affected by the lattice mismatch between the matrix and the γ'precipitates.
