采用漏磁法、多频涡流法和巴克豪森噪声法研究了应力对材料性能的影响。制备了7个不同应力水平的铁磁低碳钢试样。结果表明，室温拉伸变形后试样的屈服强度为350 MPa左右，残余应变为0.7%~ 14%，拉伸应力为100 ~ 389 MPa。
The magnetic leakage flux, multifrequency eddy current and Barkhausen noise methods were used to evaluate changes in materials properties induced by stress. Seven samples made of ferromagnetic low carbon steel with different stress level were prepared. The results showed tensile deformed samples at room temperature with a yield at around 350 MPa, residual strain between 0.7% and 14% and tensile stress from 100 MPa to 389 MPa.
