将应变扫描法应用于奥氏体不锈钢（SUS304L）的应力测量。其标距体积的尺寸为宽2mm、高0.2mm，试样的晶粒尺寸为37 μ m。由于试件晶粒粗大，测得的应力精度不够。为了改善粗晶问题，研究了三种振荡方法，如面内旋转、面外倾斜和平移。平移法可以通过改变振幅来增加晶粒数目。对于平移法，如果是10000个或更多个颗粒，则可以进行精确测量。然而，其他振荡的颗粒数量是不够的。对于平移法，试样表面和平移平面之间必须严格平行。它成功地调整了严格的平行。用该方法测量了奥氏体不锈钢喷丸后的残余应力分布。
A strain scanning method was applied to the stress measurement of austenitic stainless steel (SUS304L). The sizes of its gauge volume were a width of 2 mm and a height of 0.2mm, and the grain size of the specimen was 37 micrometers. Enough accuracy of the measured stress was not obtained due to the coarse grain of the specimen. To improve the coarse grain problem, three methods of oscillation were examined such as in-plane rotation, out-of-plane tilt and translation. The translation method can increase the number of the grains by changing the amplitude. For the translation method, the accurate measurement is possible if it is 10000 numbers or more of grains. However, the numbers of the grains by the other oscillations were not enough. For the translation method, a strict parallel between the specimen surface and the translation plane was necessary. It succeeded in adjusting the strict parallel. The residual stress distribution of the shot-peened austenitic stainless steel was measured by our method.
