A Review on Influence of Various Technological Processes on Mechanical Properties of Aluminum Alloys

摘要

Aluminum alloys are alloys in which aluminium(Al)is the predominant metal.The typical alloying elements are copper,magnesium,manganese,silicon,tin and zinc.Aluminum alloys are widely used in engineering structures and components where light weight or corrosion resistance is required.Selecting the right alloy for a given application entails considerations of its tensile strength,yield strength,fatigue strength,ductility,microhardness,weldability and corrosion resistance.The processes such as shot peening,age hardening,hydrostatic extrusion,friction stir welding,tungsten inert gas welding,quenching,sand casting,gas metal arc welding effect the various above mentioned mechanical properties of alloys.This paper gives a brief review on various processes used for improvising the mechanical properties of Aluminium alloys.
