摘要

采用磁性无损检测装置MagStar对含铁素体和奥氏体的双相不锈钢(SS2205)进行了电磁表征。通过对钢进行适当的热处理，产生不同体积分数的相，证明了该装置的效率。热处理后的SS2205钢试样的磁性参数与显微组织参数具有良好的相关性。热处理钢的磁巴克豪森辐射的磁通密度和磁均方根电压随铁素体含量的增加而线性增加。

Electromagnetic characterization of steels through magnetic NDE device

The electromagnetic characterization of dual phase stainless steel (SS2205) containing ferrite and austenite phase has been carried out by a magnetic NDE device MagStar. The efficiency of device has been demonstrated by generating different volume fraction of phases by suitable heat-treatment of the steel. A good correlation has been found between the magnetic and microstructural parameters of heat treated SS2205 steel samples. The magnetic flux density and r.m.s. voltage of magnetic Barkhausen emissions of heat treated steel increase linearly with ferrite percentage.
