| Popis: | In this study, friction stir processing (FSP) is utilized to fabricate FeCoNiCrAl high-entropy alloy reinforced Al5083 composites. The role of the reinforcement and processing pass on microstructure, microhardness, and wear properties of the composites are studied. The surface of the composites was analyzed via scanning electron microscope. The number of the processing passes acts an important role in the production of the composites via FSP technology. XRD result shows that FSP technology can be used for producing FeCoNiCrAl high-entropy alloy reinforced 5083 aluminum matrix composites which does not contain any harmful intermetallic. The properties of the composites are evaluated by microhardness and wear test. The results show that the composites possess higher microhardness and wear resistance than the Al5083 base alloy and FSPed samples without the FeCoNiCrAl high-entropy alloy particles. In all the composites, the sample produced by 5 passes reveals the highest microhardness, the best wear resistance, and the lowest friction coefficient. |
