Densification, Microhardness and Microestructural Evolution by Fast Low-Temperature Consolidation of AlxCoCrFeMnNi High Entropy Alloy

Abstract

High entropy alloys (HEA ́s) have been investigated for their attractive mechanical, microstructural and thermal properties. HEA ́s representing a wide field of study, usually these alloys are synthetized by different techniques like an arc casting, conventional sintering, plasma sintering and conventional casting [1, 2]. A new alternative consolidation route based in high frequency induction is proposes in this work, such route will provide the option to consolidate HEA at low temperature and short time, and allowing control porosity and oxidation. Thus, this work evaluates the densification, microstructure, microhardness and the aluminum addition in samples obtained by the new, fast, and low temperature consolidation process. The results are compared with conventional consolidation method
