多层镍镀层中单层的同步厚度和电极电势测定的标准试验方法 - So it is very important to understand the cyclic deformation behavior of zircaloy - 4 . in this paper , bauschinger effect of zircaloy - 4 with different metallurgical state at room temperature and 400 ? is investigated in an incremental step test and cyclic deformation test under constant strain control . bauschinger effect during cyclic deformation is described by using back stress , which is mainly responsible for bauschinger effect ; back stress is attained by using kwl " s method
本文采用单试样逐级加载循环变形和恒应变幅循环变形试验，研究了不同冶金状态、温度、氢以及固溶处理下的zr - 4合金的bauschinger效应现象；种种结果表明，影响bauschinger效应的主要因素是背应力；本文正是从背应力的角度来分析各种状态下zr - 4合金的bauschinger效应现象；背应力的计算主要通过使用kwl方法而获得。 - The experimental results is shown as followings : ( 1 ) the cyclic flow stress - strain curves in an incremental step test could be expressed as the power law relation : ( 2 ) when the strain amplitude is lower during cyclic deformation tests under constant strain control , softening firstly appears , then gradually hardens with the increasing numbers of cycle ; when the strain amplitude is higher , hardening firstly appears , then gradually softens
试验结果表明： ( 1 )循环流变应力与应变的相互关系曲线均符合幂律关系式： ( 2 )在室温下进行恒应变幅循环变形过程中，当所控制的应变幅较小时，该材料首先出现循环软化，之后随循环周次的增加直至循环失效前该材料出现了硬化现象。当应变幅较大时，该材料开始出现硬化，然后随循环周次的增加才出现软化。
