- Abstract
Residual stress is one of the important factors in the failure of brazed joints. In order to study accurately the residual stress in the brazed joints, the holding stage of brazing is taken into account. According to the microstructure of the brazed joint, a finite element model was built. The distribution of the residual stress of a 316L/BNi-2 parallel brazed joint at 1075°C for 45min was simulated. The results show that the diffusion stress of DAZ layer is compressive stress, and the maximum value is at the interface of BNi-2/DAZ. The compressive stress decreases gradually to zero along the boron diffusion direction. While both BNi-2 layer and the DAZ layer are identified as residual tensile stresses, and the tensile stress in the BNi-2 layer reaches the maximum value in the vicinity of joint corner.
