【摘要】 对304不锈钢进行了不同应变路径下的低周疲劳试验,对其循环行为进行研究。试验表明,304不锈钢在不同应变路径下表现出了不同的循环特性,在非比例路径下材料表现出附加强化现象,同时路径的非比例度越高,循环硬化现象越明显。更多还原

【Abstract】 A series of strain-controlled cyclic tests were conducted on 304 stainless steel under various strain paths to study the cyclic behavior.Present experiments have shown that different cyclic behaviors occurred on different loading paths.There is additional hardening under non-proportional cyclic loading and the degree of hardening is more obvious when the non-proportionality of strain path is larger.更多还原
