Processing of high entropy alloys with exceptionally good high temperature oxidation properties
(2023) 462116- Abstract
- The invention relates to High Entropy Alloys for high hardness and high temperature oxidation resistant applications. A new processing method has been developed to prepare the said alloys containing equiatomic ratios of Al, Co, Cr, Fe and Ni to obtain a nanocrystalline phases directly after high energy ball milling. Cr7C3 precipitates having size less than 15 nm are formed through an in-situ reaction in the process of preparation, which includes high energy ball milling with WC balls and WC vials followed by spark plasma sintering.
