Abstract
ABSTRACTThis review examines the wear characteristics of spark plasma sintered lightweight high entropy alloys (HEAs), emphasizing their distinctive qualities and prospective uses in challenging situations. HEAs are characterized by their multi‐element compositions, which provide remarkable mechanical qualities such as superior wear resistance, strength, and thermal stability. This article evaluates the importance of wear characteristics, especially in industrial applications where strength performance is essential. The influences of spark plasma sintering (SPS) on microstructure and mechanical characteristics are analyzed. The impact of processing settings on wear performance is examined, demonstrating the benefits of SPS in producing fine microstructures that improve wear resistance. The review classifies various types of wear in HEAs, including abrasive, adhesion, and fatigue, and examines the elements affecting wear performance, such as microstructure and composition. However, the experimental studies indicate that HEAs surpass traditional materials in terms of wear resistance and strength. The prospects for HEAs include chances for innovative alloy compositions, the use of computational modeling, and an emphasis on sustainability. This study provides insights into the future directions and potential strategies for achieving superior performance through processing innovations.Spark plasma sintered high‐entropy alloys are gaining attention due to their unique properties and potential applications in various fields, including aerospace, biomedical, power generation, and automotive industries. However, the wear characteristics of Spark Plasma Sintered Lightweight High Entropy Alloys remain a critical challenge.
