Abstract
Near Equi-Atomic Ti0.25-Al0.2-Mo0.2-Si0.25W0.1 high entropy alloy (HEA) with enhanced mechanical properties and good corrosion resistance was synthesized by means of spark plasma sintering technology. The influence of spark plasma sintering temperature of developed Ti0.25-Al0.2-Mo0.2-Si0.25W0.1 HEA was investigated at 800 °C, 900 °C and 1000 °C. The analysis of the morphological and microstructural characteristics of the alloy revealed the presence of bcc phase structure along with intermetallic phases of TiSi2 and Mo2Si4. Microhardness, wear and oxidation resistance of the alloy were found to be dependent on sintering temperature. The performance of the samples increased with rise in sintering temperature. The electrochemical behaviour of the alloy was tested in 0.5 M H2SO4 solution and the results showed the alloy to possess good anti-corrosion properties. The subjection of the alloy to annealing conditions at 900 °C induced formation of stable phases that improved the microhardness of the samples.
