摘　　要：汽轮机高低压联合转子锻件的高压侧要求具有高的蠕变断裂强度和高温持久强度,同时低压侧要求具有高的韧性和低的韧脆转变温度。针对联合转子锻件的这一特性,介绍了所采用的性能热处理方式--差异热处理,并对其结果进行了分析。实践证明,采用差异热处理是对转子锻件不同部位实现不同性能要求的一种新的热处理方法。The high pressure side of the high-and-low pressure combined rotor for the steam turbine is required to possess high creep fracture strength and high temperature enduring strength, while the low pressure side to have high toughness and low tough-to-brittle transition temperature. Aiming at this characteristic of the rotor forgings, this article has described the new method of the property heat treatment-diversity heat treatment and analyzed the results as well. It has been proved that the adopted diversity heat treatment is a new method of realizing different property on relevant rotor forgings locations.
