CYCLIC PLASTICITY OF CLASS A AND B HEAT-TREATED WHEEL STEELS

In order to evaluate the material properties of heat-treated wheel steels under cyclic loading, low cycle fatigue tests were conducted at room temperature on specimens taken from the rims of the wheels. The test results show that Class A and B wheel steels experience significant cyclic softening over the strain ranges studied. The cyclic softening is particularly pronounced at low strain levels. Due to the pronounced cyclic softening at low strain levels the steels will plastically deform, even at stresses below the monotonic elastic limits. Quantitative fatigue properties, which can then be used to predict fatigue lives of various components of wheels under complex service environments, are also obtained from the low cycle fatigue tests.
