| 摘 要： | 采用金相探针法和高温拉伸试验研究S对HasteuoyC-4合金凝固偏析及热塑性的影响。结果表明，随着S含量的增加，导致固液两相区、温度范围和偏析程度明显加大，引起合金的热塑性降低。因此，降低合金S的偏析有利于合金的锻造性能。

| Abstract: | Effects of S on solidification segregation and hot plasticity of Hastelloy C 4 alloy were examined by electron probe and hot tensile test. The results showed that the solid liquid phase zone, temperature interval and segregation degree may be obviously enlarged with increasing S content so as to reduce the hot plasticity of the alloy. Therefore, the decrease in S content in the alloy is beneficial to the forging performance of the alloy. |
