Abstract Scope |
Development of lightweight Al alloy with high electrical conductivities, tensile properties and low cost has become an urgent task for market expansion of battery-powered electric vehicles in the past few years. Manganese (Mn) is one of the alloying elements often used in wrought Al alloys (3xxx series), which can ensure uniform deformation and enhance strengths, compared to pure aluminum. This is because Mn has a low maximum solubility of 1.25 wt% in Al under equilibrium solidification and forms Al6Mn dispersoid as a strengthening phase. In this paper, the effects of Mn on the electrical and tensile properties of Al alloys are reviewed. The electric conduction principles and microstructure characteristics of Mn-containing Al alloys are presented. The strengthening mechanisms are discussed. The effects of cooling rates on the tensile properties of Mn-containing Al alloys are highlighted. |
