The Effects of Annealing Temperature on the Microstructure and Properties of Cold-Rolled 5083 Aluminum Alloy

Abstract:

The effects of annealing temperature on the strength and corrosin properties of cold-rolled 5083 aluminum alloy (ε=60%）were investigated. The results show that the tensile strength of the alloy decreases with rising annealing temperature. The alloy shows ductile cracking in dry air and brittle cracking in 3.5%NaCl aqueous solution. The alloy reserves the most positive electrical potential at 200°C, and low SCC susceptibility at 200、250°C when annealed, but reserves relative high SCC susceptibility at 100, 150,300 and 350°C, which can be attributed to the difference shape and distribution of β-phase annealed at different temperature.
