辙叉用高锰钢的循环变形与硬化
Cyclic deformation and hardening of Hadfield high manganese steel for crossing
摘要
Abstract
The cyclic stress/strain behavior, the peak and valley stress responses, as well as the variations of hardness of the samples taken from an actual Hadfield high manganese steel for crossing during cyclic deformation were investigated by means of strain-controlled low cycle fatigue tests. The results indicate that obvious cyclic hardening occurs in the investigated steel during initial cyclic deformation, and the peak and valley stresses reach a steady state with increasing the number of cycles. The cyclic hardening rate increases whereas the number of cycles to reach a saturated stress state decreases with increasing the applied strain amplitude. Additionally, the hardness of the cyclically deformed Hadfield high manganese steel increases largely, as compared to the unde-formed Hadfield high manganese steel.关键词
