| Abstract Scope |
In the present study, low-density multicomponent alloys based on the Mg-Al system were investigated in order to develop advanced lightweight alloys. For the current alloy development, the alloy design was based on multi-element alloying approach to increase the mixing entropy in order to be categorized as medium entropy alloys (MEAs). In new alloys developed in this study, the concentration of each alloying element remained ≥ 5 at % with Mg (60 and 70 at.%) as dominant base material. The calculated mixing entropy in the new alloys was ≥ 1R (R is gas constant, 8.314 J/K mol), qualifying them as medium entropy alloys. The new magnesium based medium entropy alloys, Mg60Al20Cu10Zn5Mn5 and Mg70Al10Cu10Zn5Mn5, were synthesized using disintegrated melt deposition technique. Following synthesis, characterization studies were done on the materials. Particular emphasis was placed to examine and understand the microstructural development and resultant influence of microstructure on mechanical properties. |
