对316L不锈钢分别进行了室温、高温单轴应变控制和应力控制下的系统循环试验,揭示和分析了循环应变幅值、应变幅值历史以及温度历史对应变循环特性的影响以及应力幅值、平均应力和温度及其历史对循环棘轮行为的影响。研究表明,无论是单轴应变循环特性还是非对称单轴应力下的棘轮效应不仅依赖于当前温度和加载状态,而且还依赖于温度和加载的历史,并得到了关于 316L不锈钢室温和高温单轴循环行为的若干有意义的结果。
The 316L stainless steel was subjected to uniaxial strain control at room temperature and high temperature and the system cycle test under stress control respectively. The effects of cyclic strain amplitude, strain amplitude history and temperature history on the strain cycling characteristics and stress amplitudes, average Effect of stress and temperature and its history on the ratchet behavior. The research shows that the ratcheting effect in both uniaxial and cyclic uniaxial uniaxial stress depends not only on the current temperature and the loading state but also on the temperature and the loading history. Some Meaningful Results of Cyclic Behavior.
