Abstract

AbstractCreep tests have been carried out on the three principal transformation structures of a Cr-Mo-V rotor steel which had been given a common tempering treatment. Although creep strength varied with transformation structure, being lowest for martensite and highest for bainite, a single form of σ-έ-T relationship was obtained which can be derived from a solute-drag model.

1% Cr-Mo-V转子钢的蠕变性能
摘要对经普通回火处理的Cr-Mo-V转子钢的3个主要相变组织进行了蠕变试验。蠕变强度随相变组织的变化而变化,马氏体的蠕变强度最低,贝氏体的蠕变强度最高,但从溶质-阻力模型可以得出单一的σ- t关系。
