Corrosion fatigue behaviour of aluminium 5083-H111 welded using gas metal arc welding method

Abstract

Aluminium and its alloys are widely used as engineering materials on account of their low density, high strength-to-weight ratios, excellent formability and good corrosion resistance in many environments. Pure aluminium has a density of only 2.70 g/cm3, as a result, certain aluminium alloys have better strength-to-weight ratios than high-strength steels. One of the most important characteristics of aluminium is its good formability, machinability and workability. It displays excellent thermal and electrical conductivity, and is non-magnetic, non-sparking and non-toxic. This investigation focused on one popular wrought aluminium alloy, namely magnesium-alloyed 5083 (in the strain hardened -H111 temper state).
