本文把单峰测定嵌镶块大小与微观应变的Voigt函数法应用于X射线应力测定仪,并编制了衍射峰形校正微机程序,使X射线应力测定仪能对实际工件进行现场测定。实验结果表明:当衍射峰形状因子W/B不太大时,与传统的近似函数法较接近,而当W/β太大时,必须对K值进行修正。 In this paper, the Voigt function method of unimodal determination of mosaic block size and microstrain was applied to X-ray stress analyzer, and the diffraction peak shape correction microcomputer program was compiled to make the X-ray stress analyzer measure the actual workpiece on site. The experimental results show that when the diffraction peak shape factor W / B is not too large, it is close to the traditional approximate function method, and when W / β is too large, the value of K must be corrected.
