摘要：
A high level of recognition has been given to high-entropy alloys (HEAs) in recent years because of their excellent properties over conventional superalloys. Consequently, research focus has shifted to the development and characterization of high-performing HEAs. The objective of this work was to develop and characterize Ti-36-Al-16-V-16-Fe-16-Cr-16 HEA with the aim of determining its performance over conventional superalloys in engineering applications. Spark plasma sintering was the fabrication technique used. SEM-EDS and XRD were used in the characterization while a nano indenter and tribometer were used in the Vickers hardness and wear testing, respectively. Results obtained showed that a sintering temperature of 1000 degrees C was optimal. The developed HEA had a Vickers hardness improvement of 136% over the Ti6Al4V alloy; and a wear rate improvement of 157% over Inconel 718 alloy, and 614% over TiAl alloy. It was concluded that the developed HEA can perform much better than conventional Ti6Al4V and other superalloys in engineering applications.
