| 摘 要： | 研究了LZ50车轴钢的循环相关特性,循环疲劳特性及循环应力-应变关系。试验结果表明:LZ50车轴钢的循环疲劳特性曲线及循环应力-应变曲线很好地符合双对数线性关系;其循环相关特性表现为先循环软化,稳定后又发生循环硬化,而且循环软化和循环硬化的程度随控制应变的不同而不同。

| Abstract: | The cyclic properties,the fatigue properties and the cyclic stress-strain curves of LZ50 axletree steel have been investigated in this paper.The test results show that the fatigue property curve and the cyclic stress-strain curve of LZ50 axletree steel perfectly conform to double logarithm linear relationship.Its cyclic properties first show cyclic softening,after stabilizing,then cyclic hardening.The state of cyclic softening and cyclic hardening will vary along with strain level. |
