| Abstract Scope |
One important aspect to achieve significant use of lightweight metals in the automobile industry is the development of a robust technique for joining dissimilar metals. Friction-stir Assisted Scribe Technique (FAST) is one of the viable methods to do so. In this work, FAST was used to join AZ31 magnesium alloy to DP590 steel. The main aim of this study is to understand the mechanical properties and performance of a FAST joint. Tensile tests were performed by cutting dogbone samples in the direction perpendicular and parallel to the weld. Finite element method based computational model was introduced to understand the effect of mechanical interlocking between two materials on the joint performance. The interfacial bonding was modeled using a cohesive zone model. The geometry of the hook feature was adapted in the FEM model using SEM images. Finally, correlating the contribution from mechanical and metallurgical bonding to understand the basic joining phenomenon. |
