본문내용
AbstractThe high entropy alloys (HEAs) are the latest advanced alloy and have unique properties. Because the HEAs contain the multicomponents, their high entropy stabilizes the solid solution and disturbs the intermetallic compounds. So, they have enhanced mechanical properties in high or low temperatures. Also, they have high corrosion resistance, high electrical resistivity, and low thermal conductivity. Therefore, the HEAs can be used widely in extreme conditions. Last, they have economic feasibility because half of their components are not high-priced elements.
1. Introduction
Metals generally can’t have both hardness and ductility. Some metals which have great hardness are brittle, so they can be broken easily. Although other metals have excellent toughness, they are not hard and deformed easily. So, metallurgists developed alloys. Properties of the alloys are controlled by composition, so we can get materials of appropriate properties.
