Fabrication of Al/Mg Bimetallic Thin-Walled Ultrafine-Grained Tube by Severe Plastic Deformation

Multilayer composites have recently attracted considerable attention due to their ability take advantage of the benefits various metallic materials simultaneously. The present study is first use parallel tubular channel angular pressing (PTCAP) as a severe plastic deformation method fabricate bimetal Al/Mg tube. This process was applied on commercially pure aluminum along with an AM60 magnesium alloy at temperature range 250-400 °C. According microstructural and mechanical tests, there strong bond between layers besides grain refinement after process. Additionally, microhardness examinations showed that excellent homogeneity in addition dramatic increase hardness bimetallic PTCAP processed Scanning electron microscope energy-dispersive x-ray spectroscopy analyses interface also results shear strength test by increasing temperature, diffusion rate increases. For instance, significant bonding 30 MPa achieved specimen 400 Therefore, these investigations substantiate can be used appropriate cladding technique for obtaining simultaneous microstructures sufficient production tubes.
