摘要

The low cycle fatigue tests of 30Cr2MoV steel at room temperatures were performed. The softening properties of studied steel were investigated. Based on the experimental results, the quantitative relationships between the hardness and fatigue damage were established. A modified Mason-Coffin equation including the effect of aging was derived. A damage calculation method by hardness value to assess the remaining life of the metals was proposed. Both experimental and theoretical results show that it is valuable to predict the remaining life of steam turbine rotor by the measurement of hardness.
