利用黄铜Ⅱ型和Ⅲ型试样研究了应力腐蚀裂纹形核位置和扩展方向与应力分量的关系。结果表明,裂纹在最大正应力处形核,扩展方向与最大正应力相垂直.在Ⅲ型试样中,氨浓度对裂纹扩展形态有影响,氨浓度较高时,由于均匀腐蚀的作用,在45°面上的裂纹很不明显;在氨浓度较低时,则可看到沿试样圆周有许多45°面裂纹,裂纹...

The effects of stress components on nucleation sites and propagation directions of stress cor- rosion cracks in brass were investigated with specimens under mode Ⅱ and mode Ⅲ loadings. The results indicated that under mode Ⅱ loading,stress corrosion cracks nucleated on the site with maximum normal s...
