用激光云纹干涉法研究了黄铜在氨水溶液中应力腐蚀过程中缺口前端位移场和应变场的变化结果表明，在应力腐蚀裂纹萌生前，溶解（腐蚀）过程本身能使缺口前端塑性区增大，与此同时也使塑性区中各点的塑性变形量增大，即溶解过程本身能促进塑性变形。
The change of displacement field and strain field in the front of notch of brass in stress corrosion process of ammonia solution was studied by laser moire patterning. The results show that the dissolution (corrosion) process itself can increase Large, at the same time, the plastic deformation at various points in the plastic zone also increases, that is, the dissolution process itself can promote plastic deformation.
