Intergranular Corrosion and Microstructural Evolution in a Newly Designed Al-6Mg Alloy

Abstract: In this work, the microstructure and corrosion behavior of a novel Al-6Mg alloy were investigated. The alloy was prepared by casting from pure Al and Mg+Al2Ca master alloy. The ingots were homogenized at 420 °C for 8 h, hot-extruded and cold-rolled with 20% reduction (CR20 alloy) and 50% reduction (CR50 alloy). The CR50 alloy exhibited a higher value of intergranular misorientation due to a higher cold rolling reduction ratio. The average grain sizes were 19 ± 7 μm and 17 ± 9 μm for the CR20 and CR50 alloys, r… Show more

“…Al-Mg alloys are usually preferred as welding fillers for high-strength aluminum alloys due to their suitable weldability and strength [8][9][10]. A combination of high strength and suitable formability in non-heat treatment strengthening Al-Mg alloys can be achieved by refining the grain size and introducing precipitates in the microstructure.…”
