摘要

采用漏磁通、多频涡流和巴克豪森噪声等方法评价应力对材料性能的影响。制备了7种不同应力水平的铁磁低碳钢试样。结果表明:室温拉伸变形后的试样屈服在350 MPa左右，残余应变在0.7% ~ 14%之间，拉伸应力在100 ~ 389 MPa之间。

Fusion of electromagnetic inspection methods for evaluation of stress loaded steel samples

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.
