采用电磁阻抗法对SUS304型不锈钢（SUS304钢）在不同拉应力值下的渗透性能进行了评价。在拉伸应力为0、70、140 MPa的情况下，通过5% ~ 40%的预应变改变试样的马氏体分数，测量了SUS304钢的阻抗-磁场曲线与磁导率-磁场曲线的对应关系。测量了长度（拉伸）方向和宽度方向的阻抗曲线。结果表明：SUS304钢的拉伸方向为马氏体相磁硬轴；SUS304钢渗透率的外加应力敏感性受体积分数、残余应力、马氏体相取向角的应力分布及其相互作用的影响。
The permeability properties of type SUS304 stainless steel (SUS304 steel) were evaluated under different values of tensile stress using the electromagnetic impedance method. The impedance–magnetic-field curve of SUS304 steel, which corresponds to the permeability–magnetic field-curve, was measured under tensile stresses of 0, 70, and 140 MPa for specimens subjected to prestrains of 5% to 40% to change the martensite fraction. The impedance curves were measured in the length (tensile) direction and the width direction. The results showed that the tensile direction was the magnetic hard axis of the martensite phase in SUS304 steel. The applied stress sensitivity of the permeability in SUS304 steel was affected by the volume fraction, residual stress, stress distribution according to the orientation angle of the martensite phase, and their interactions.
