Numerical Simulation and Experimental Investigation of Residual Stress in 06Cr19Ni10 Austenitic Stainless Steel Weld Joint with Effects of Strain-Strengthening
Applied Mechanics and Materials, 2016Co-Authors: Lan Qing Tang, Hui Fang Li, Xiao Xiao Wang, Cai Fu QianAbstract:In this paper, Finite Element Modeling (FEM) using Marc software was carried out to investigate the strain-strengthening effect on Residual Stress in 06Cr19Ni10 austenitic stainless steel weld joint made by MIG Welding. The model prediction of Residual Stress was validated by X-ray Diffraction (XRD) method. It is found that there is a good agreement between the model predictions and the experimental results. The strain-strengthening can significantly improve the distribution of Residual Welding Stress. Specifically in weld zone and the heat-affected zone (HAZ), Residual Stress decreases with increasing strain-strengthening level.

Mixed mode notch-crack fatigue propagation in the Welding zone of 06Cr19Ni10 austenitic stainless steel: Effect of strain strengthening
International Journal of Materials Research, 2016Co-Authors: Lan Qing Tang, Cai Fu Qian, Hui Fang LiAbstract:In this work, mixed mode fatigue crack propagation in the Welding zone of 06Cr19Ni10 austenitic stainless steel was experimentally investigated. The effects of strain strengthening on crack growth paths and growth rates were studied. The experimental results demonstrated that a new crack initiated from the notch-crack tip and propagated in the direction perpendicular to the loading direction, suggesting a change of the crack mode from mixed mode to Mode I. Strain strengthening has no effect on the crack growth paths, while it does have some effect on the crack growth rates. The metallographic results indicate that the fraction of transformed martensite increases with strain-strengthening level. Finite element analysis results reveal that strain strengthening can significantly change the distribution of the Residual Welding Stress.
