| 摘 要： | 研究了熔体过热处理对M963铸造镍基高温合金凝固偏析的影响。结果表明，熔体过热处理对Al，Co和Ni的偏析影响不磊；1923K，5min熔体过热处理，使Ti，Nb和W的偏析增大，Mo和Cr的偏析减小。元素偏析程度的改变足由于合金熔体结构的变化引起的。

| Abstract: | The effect of melt overheating treatment on the solidification segregation of M963 cast Ni-base superalloy has been studied. The results show that the melt overheating treatment has little effect on the segregation of Al, Co and Ni; and the melt treatment at 1 923 K for 5 min caused an increase in segregation of Ti, Nb and W and a decrease in segregation of Mo and Cr obviously. It is suggested that the change of segregation is attributed to the change in the melt structure of the M963 superalloy. |
