A new era for applications of multi-principal element alloys in the biomedical field.

In today's context of an aging population and the gradual decline of human physiological functions, we are increasingly confronted with health issues such as fractures and arthritis. The demand for implants has risen correspondingly, while traditional alloys have become insufficient to meet the developmental needs of this era. The emergence of multi-principal element alloys (or high-entropy alloys) in 2004 has attracted significant attention, leading to extensive research due to their remarkable four core effects.
