| Abstract Scope |
In this technical presentation the results of a study on development of low-density multicomponent alloys, based on the Mg-Al system, will be highlighted and discussed. Alloy design was based on use of multi-element alloying approach with the prime intent of increasing the mixing entropy so as to be categorized as medium entropy alloys (MEAs). For the new alloys developed, the concentration of each alloying element remained at ≥ 5 atomic percent with magnesium [60 to 70 atomic percent] being the dominant base material. The calculated mixing entropy of the newly developed alloys was ≥ 1R [R = gas constant, 8.314 J/K mol], thereby qualifying each of the alloys to be a medium entropy alloy. The developed magnesium-based medium entropy alloys, Mg60Al20Cu10Zn5Mn5 and Mg70Al10Cu10Zn5Mn5, were synthesized using the technique of disintegrated melt deposition [DMD]. Subsequent to synthesis, characterization studies were done to understand microstructural development and influence on mechanical properties. |
