Investigating the Mechanical Properties of Aluminum Alloy Ultra-Fine Grained Metals by Fluid-Solid Coupling Method

Abstract

This research examines the mechanical characteristics of metal materials using the FSC (Fluid-solid coupling) technique. It primarily investigates the formation of a regular FSC non-smooth surface by the 7A05 deformed aluminum alloy after laser treatment. The mechanical characteristics of the manufactured aluminum alloy ultrafine grained metal materials are investigated by altering various laser settings, coupling patterns, and cell distribution modes. The findings demonstrate that the tensile strength of aluminum alloy increases by 37.21% and 44.14%, and the fracture strength increases by 38.69% and 46.73%, respectively, when the chip thickness compression ratio is 1.2 and 2.2. According to the study, extruding aluminum alloy improves its Vickers hardness, tensile strength, friction, and wear qualities to varying degrees.
