Properties of Al-6Mg-xSc (x = 0 to 0.6 wt.%) Alloy Subjected to Thermal Treatment: A Review

Аннотация

Aluminum–magnesiumalloys are regularly used to manufacture different types ofsheets, automotive trims, and architectural components, which are very intricate in shape.Additionally it isimportant due to their excellent properties of high-strength to weight ratio, corrosion resistance and weldability. Magnesiumincreases the strength of the alloys but there is a tendency to form β-phase Al₈Mg₅ compound, usually denoted as Al₃Mg₂ precipitates along grain boundaries to facilitate intergranular fracture. Numerous studies have been conducted on these alloysto make their use potential as different places. The use ofscandium in Al-Mg alloys is meant for taking the advantage of grain refinement along with the unique precipitation strengthening behavior through the formation of Al₃Sc precipitates with aluminum, a stable LI₂ phase coherent with the matrix. The purpose of this paper is to review and discuss recent developments on Al-6Mg alloy through scandium addition at different levels under thermal treatment.
