Abstract
High-entropy alloys (HEAs) have excellent mechanical properties, as a kind of advanced materials. The HEAs not only have high strength and high hardness at room temperature, but also has good thermal stability and maintain excellent mechanical properties at high and low temperature. In addition, high-entropy alloy fibers and high-entropy films, as the derivatives of HEAs, also have many excellent properties. HEA fibers displayed better properties compared with the as-cast bulk HEAs. Besides, the HEFs can be regarded as a new kind of films and a method of high throughput screening, which can get many samples with different compositions in one experiment. In summary, HEAs have excellent mechanical properties at different temperature ranges, but their mechanical properties are also highly dispersed.
