| Abstract Scope |
In this presentation, the results of a recent study on two light weight multi-component high entropy alloys (HEAs) were synthesized and consisted of six constituent elements. The high entropy alloy having a chemical composition of Mg35Al33Li15Zn7Ca5Y5 (atomic percent.) had a density of 2.25 g/cm3, while the high entropy alloy having a chemical composition of Mg35Al33Li15Zn7Ca5Cu5 (atomic percent) had a density of 2.27 g/cm3. The conjoint and mutually interactive influences of non-equiatomic composition, high entropy of mixing and low density was applied to designing the alloy systems. The technique of disintegrated melt deposition (DMD) was used to synthesize the two alloys followed by characterization studies of the as-synthesized alloys. This presentation will examine microstructural development of the two light weight high entropy alloys. The formation and presence of phases and gradual evolution of microstructure was studied by interchanging yttrium and copper. Microstructural observations and microhardness test results will be highlighted. |
