Abstract

High-entropy alloys represent a significant advancement in the field of material science. These alloys offer a combination of high strength, excellent corrosion resistance and unique thermal properties, which makes them suitable for a wide range of applications across various industries. In this study, it is aimed to design and produce materials that can be used in high temperature applications with the concept of high entropy alloy (HEA). FeNiCuTiW high entropy alloys with different atomic percentages of Tungsten (W) were produced by arc melting. Hardness tests, optical microscopy and XRD (X-ray Diffraction) analysis were carried out on specimens. Results show that the alloys compose of three different phases i.e. two bcc (W based and Iron based) and one fcc structure (Cu based) and the increase in W content increases hardness up to 0.8 mol but at equal atomic ratio, the hardness drop dramatically due to the excessive W segregation.
