Abstract Scope |
Inconel and stainless steel are widely used for high temperature applications. Rotary friction welding is a solid-state joining technique, which is capable to join dissimilar materials. However, the fatigue loading response of the dissimilar joints is not fully understood. In the present study, Inconel 600 and SS 316 rods are rotary friction welded. The dissimilar joints are subjected to tensile and fatigue crack propagation tests. The crack growth rate for dissimilar joint is higher than the base materials (Inconel 600 and SS 316). Further, an extended finite element method based numerical model is developed to capture the fatigue crack growth behavior of the dissimilar joint. The numerical model incorporates the material heterogeneity of the dissimilar weld and well captures the experimental observations. This work helps to understand the mechanical performance and structural integrity of dissimilar rotary friction welded joints of Inconel 600 and SS 316. |
