Physical, Mechanical and Thermal Behaviour of High Entropy Materials

Abstract

Received: 5 Decemebr 2019 Accepted: 19 February 2020 High-entropy alloys (HEAs) are alloys that are formed by mixing equal or relatively large proportions of (usually) five or more elements. Development of high entropy material is one of the biggest challenging areas in materials and design. However, high entropy materials exhibit very good mechanical properties. In the present investigation, an attempt was made to develop high entropy material by simple casting technique using Cr, Mn, Fe, Al and Ni with equal weight percent. Squeeze pressure was applied on developed Cr0.20Mn0.20Fe0.20Al0.20Ni0.20 high entropy alloy to eliminate porosity and improve the grain structure. Microstructure image of Cr0.20Mn0.20Fe0.20Al0.20Ni0.20 showed fair interfacial bonding between the alloys after squeeze pressure. Tensile strength, hardness was significantly improved of developed high entropy material. Physical and thermal behaviour such as corrosion loss and material sustainability were also observed to see the effect of different alloys interfacial reaction layer.
