Abstract

Characteristic Properties of high entropy alloys (HEAs) have been adjudged to be affected by the processing route. Hence, the functionality and efficiency of HEAs are partly dependent on their fabrication technique. Therefore, this study was aimed at reviewing the available production routes of HEAs and their strengths and weaknesses in order to propose the most suitable techniques to be adopted. The resource materials were sourced from Scopus database and google scholar website of articles published in the last five years, laying more emphasis on the most recently published works. In the study, it was concluded induction melting is the best liquid processing route. More so, non-conventional sintering like spark plasma sintering is much better than conventional sintering. In additive manufacturing, 3D printing and laser cladding equip their products with enviable properties. If precision and purity are required, laser cladding should be adopted, while 3D printing is used when customization, rapid prototyping and high design freedom are of essence.
