高铬铸铁中残余奥氏体体积分数的检测对保证热轧等耐磨构件的质量和硬度具有重要意义。随着残余奥氏体体积分数的增加，铸铁的渗透性和导电性降低。因此，通过检测电磁特性的差异来检测残余奥氏体是可能的。然而，检查并不容易，因为铸铁的渗透性通常是不均匀的。因此，电磁检测信号具有磁噪声。本文采用基于三维边缘的六面体非线性有限元法，研究了降低磁导率不均匀性对大磁噪声影响的检测技术和测量残余奥氏体的检测技术。此外，还进行了实验验证。
The inspection of volume fraction of retained austenite in the high chromium cast iron is important in keeping the quality and hardness of abrasion proof components as a steel of hot-rolling etc. The permeability and the conductivity of the cast iron are decreased when the volume fraction of retained austenite is increased. Therefore, the inspection of the retained austenite is possible by detecting the difference of the electromagnetic characteristic. However, the inspection is not easy, because the permeability of the cast iron is usually nonuniform. As a result, the signal of the electromagnetic inspection has a magnetic noise. In this paper, the inspection technique for reducing the effect of the nonuniformity of the permeability on the large magnetic noise, and that for measuring the retained austenite is examined using 3-D edge-based hexahedral nonlinear finite element method (FEM). In addition, the experimental verification is also carried out.
