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,使其能应用 X 射线应力测定仪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/β不是太大时,和传统的近似函数法符合较好,而当 W/β太大时,存在较大误差,应对 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 prepared, which can make the field measurement of the actual workpiece by X-ray stress analyzer. The experimental results show that when the shape factor W / β of the diffraction peak is not too large, it is in good agreement with the traditional approximation function method. When the W / β is too large, there is a big error and the K value should be corrected.
