High entropy alloys (HEAs) materials possess outstanding mechanical and corrosion properties for advanced engineering applications such as aerospace, chemical plants and furnace parts. In this work, TiAlMoSiW, Ti0.25AlMoSi0.25W0.1 and Ti0.3AlMoSi0.3W0.1 HEAs are developed via spark plasma sintering. The developed HEAs are consolidated at 1000oC with holding time of 8 min and applied pressure of 50MPa. SPS technique is known to offer enhanced densification and controlled grain growth of the alloy with minimal porosities. Scanning electron microscope coupled with energy dispersive spectrometer (SEM/EDS) and X-ray diffractometer (XRD) are used to analyze the morphological evolution and phases formed respectively. Microhardness and tribological properties of the synthesized alloys were analyzed by means of diamond base micro hardness tester and tribometer (Rtec) respectively. Corrosion resistant properties of the synthesized HEAs was evaluated by means of 101 AUTOLAB potentiostat. The synthesized HEAs shows a good mechanical properties and high corrosion resistance properties.
