Optimization of squeeze casting process parameters for AC2A aluminium alloy through experimental studies

Abstract

Alloys of light metals such as aluminium titanium and magnesium are extensively used in automotive aerospace and military sectors since their light weight leads to reduced energy consumption increased fuel efficiency and better environmental protection Particularly in automotive and aerospace sectors utilization of aluminium alloy components has been increased during the last two decades due to their desirable properties such as high strength to weight ratio good castability good machinability and excellent corrosion resistance Aluminium alloys are generally processed through sand casting investment casting continuous casting centrifugal casting gravity die casting and pressure die casting Die casting techniques are widely employed for producing intricate shaped castings in aluminium foundries Generally they exhibit several casting defects such as gas porosities shrinkage porosities segregations hot tears etc while processing some aluminium alloys for the production of intricate shaped parts
