Abstract
High-entropy alloys (HEAs) have become a research hotspot in recent years. The nature of the multi-principal elements, high mixing entropy, and mutual interactions between elements render this novel material outstanding mechanical and functional properties, in which most research efforts are focused on mechanical properties. There are many aspects that can influence the mechanical behavior, such as constituent elements and fabrication methods. This paper will mainly summarize and discuss the effects of constituent elements and fabrication techniques on the mechanical properties of HEAs, by reviewing relevant papers, to have a better understanding of the variation ranges resulting from the above two factors and the reasons for the properties changes. Future directions are provided at the end of this article.
