| Abstract Scope |
The need for lightweight metals has directed attention toward the use of bimetallic components, which combine two distinct material properties into a single component. A novel method, known as friction stir backward extrusion (FSBE) has been introduced for the fabrication of bimetallic (steel-aluminum) tubular components. This method can be adopted for the fabrication of bimetallic rings, which are subjected to compressive and shear loads during operation. In this study, the interface bonding was evaluated through flattening and push-out tests, and the flattening process was simulated using Deform 3D to understand the separation between cladded layer and tube. The results show that the heat generated during the process leads to diffusion bonding between the substrate and cladding material, as well as reduces the hardness of the cladded aluminum compared to base aluminum, which enhances the ductility and allows it to undergo significant plastic deformation without any fracture. |
