| Abstract Scope |
Bi-metallic tubes are generally used where two distinct properties are required at the outer and inner part of the tube such as electrical/thermal conductors. In this investigation, shear assisted processing and extrusion (ShAPE) was employed to fabricate bi-metallic tubes from dissimilar Al alloys. Material flow during co-extrusion of dissimilar Al alloys was investigated using micro computed tomography. Detailed microstructural characterization of the interface and various locations of the bi-metallic tubes were carried out using scanning electron and transmission electron microscopy techniques. A defect-free, metallurgically bonded interface between core and shell was observed. Furthermore, hardness and tensile properties of the bi-metallic ShAPE tubes were examined in extruded and heat treated conditions. |
