Powder metallurgy technique is widely used in aerospace, medical sector, and automobile engineering. It is a simplest method used for fabricating components with high entropy materials. In this article, the mechanical and microstructural properties of the high entropy alloys (HEAs) materials are observed. The certain process parameters are such as particle size, sintering (temperature, pressure and time), blended speed with time and heating rate are also observed. This review article will help the researchers to find the results obtained by various experiments performed previously through powder metallurgy (PM) technique.
