High-entropy alloys—a new era of exploitation

WebAbstract. High entropy alloys (HEA) are composed of elements with atomic concentrations between 5% and 35%, unlike conventional alloys. This new generation of metallic materials has found utilization areas in many engineering applications due to … WebAbstract: In 1995, Yeh suggested the formation of an alloy made up of at least five metallic elements which have large mixing entropy solutions with many elements forming solide alloys. This alloy appeared because traditional alloys are characteised by high fragility and are difficult to process.
