本文借助X-射线应力仪,采用半高宽中点及高斯曲线定峰方法,测量SiCw/6061A1复合材料基体中的热错配应力,结果表明,高斯曲线具有较高的定峰精度,是复合材料X-射线应力测量中的理想定峰方法。
In this paper, the thermal mismatch stress in SiCw / 6061A1 composite matrix was measured by means of X-ray stress meter, median half-height width and Gaussian curve determination. The results show that the Gaussian curve has high peak fixing accuracy and is a composite material X The ideal peak determination in ray stress measurement.
