Abstract

Using a nondestructive testing method based on hysteresis behavior, the structural-mechanical dependence of the coercive force of 35CrMo steel components was compared with that of standard specimens. As described in the magnetic Jiles–Atherton model, the magnetic coercive force of the cylinders was inversely proportional to the grain refinement, which was validated by means of metallographic examination and hardness tests. Simultaneously, this study presented an experimental validation by destructive testing for determining the relationship between the measured magnetic parameter and the property of concern and a linear correlation between coercive force and hardness. These observations provide a method to quickly and nondestructively evaluate the mechanical properties of steel components.

评定钢瓶力学性能的磁法

采用基于迟滞特性的无损检测方法，比较了35CrMo钢构件矫顽力与标准试样的结构-力学相关性。根据磁Jiles-Atherton模型，圆柱体的磁矫顽力与晶粒细化成反比，通过金相检验和硬度测试验证了这一点。同时，本研究通过破坏性试验验证了测量的磁性参数与关注的性质之间的关系以及矫顽力与硬度之间的线性关系。这些观察结果为快速、无损地评价钢构件的力学性能提供了一种方法。
