The Investigation of Hot Extrusion Process Parameters on Microstructure and Mechanical Performance of Aluminium Alloy in Biomedical Industry
Aluminium alloy 7075 is chosen as the material to be investigated to replace stainless steel as the material of hyperthermic needle. Hot Direct Extrusion process is famous for reducing the size of the grain to enhance the mechanical properties of the alloy. The process parameters are investigated th...
