喷丸强化通常被认为是防止疲劳或应力腐蚀引起的开裂的明智方法。在本文中，我将介绍三种奥氏体材料的静应力腐蚀试验结果。拉伸试验用的试样分别为1.4571 （X6CrNiTi 1712-2）、1.4541 （X6CrNiTi1810）和1.4462 （X2CrNiMoN22-5-3）材料。利用喷丸强化软件选择不同的喷丸强化参数。残余应力的计算值与实测值非常接近。
Shot Peening is usually considered as a sensible method to prevent cracking related to fatigue or stress corrosion. In this paper, I will present the results of static stress corrosion tests of three austenitic materials. The specimens for tensile testing were made from the materials 1.4571 (X6CrNiTi 1712-2), 1.4541 (X6CrNiTi1810) and 1.4462 (X2CrNiMoN22-5-3). The different shot peening parameters were selected by the Peenstress" Software. The calculated and measured residual stress profiles are very close.
