摘要
通过Gleeble 3500型热模拟试验机研究了变形温度、变形量对不同成分GH4133B合金在1s-1应变速率下热压缩变形行为的影响。结果表明:其变形抗力随着变形温度的升高而迅速降低;随变形温度的升高和变形量的增大,动态再结晶进行得更充分;碳质量分数为0.062%时合金的压缩性能最好,降低铝、钛、铌质量分数可使合金变形抗力降低;碳质量分数为0.062%时合金的最佳变形温度为1 100℃,变形量为50%。
The effects of deformation temperature and distortion on compression deformation behavior of GH4133B alloy with different compositions under the condition of strain ratio of 1 s-1 were studied by Gleeble 3500 thermol simulation tester. The results show that the deformation resistance reduced rapidly with increase of deformation temperature. Increasing deformation temperature and distortion, dynamic recrystallization led to more adequate proceeding. The compression properties of the alloy with carbon mass fraction of 0. 062% were best, and decreasing the content of A1, Ti and Ni resulted to decrease of deformation resistance. The optimum deformation temperature was 1 100℃ and deformation distortion was 50%.
