“…At the same time, in order to further explore Ti-based HEA with biomedical prospects, the biological properties of other elements added to Ti-Nb-Ta-Zr HEA were studied by Stráský et al (2017) . Besides, Popescu et al (2018) prepared a novel Ti 40 Nb 20 Zr 20 Ta 10 Fe 10 HEA that was showed the outstanding corrosion resistance compared with Ti6Al4V. Cao et al (2020) prepared TiNbTa 0.5 ZrA l0.5 HEA by PM and found that after hot-working, the TiNbTa 0.5 ZrA l0.5 HEA transformed from the initial BCC phase to BCC and HCP phase with 1740 MPa high-pressure yield strength ( Chen et al, 2019 ).…”

With the continuous progress and development in the biomedicine field, metallic biomedical materials have attracted the considerable attention of researchers, but the related procedures need to be further developed. Since the traditional metal implant materials are not highly compatible with the human body, the modern materials with excellent mechanical properties and proper biocompatibility should be developed urgently in order to solve any adverse reactions caused by the long-term implantations. The advent of the high-entropy alloy (HEA) as an innovative and advanced idea emerged to develop the medical implant materials through the specific HEA designs. The properties of these HEA materials can be predicted and regulated. In this paper, the progression and application of titanium-based HEAs, as well as their preparation and biological evaluation methods, are comprehensively reviewed. Additionally, the prospects for the development and use of these alloys in implant applications are put forward.

CoCr and CoCrMo-based alloys are commercially used in the industry especially for high wear resistance and superior chemical and corrosion performance in hostile environments. These alloys were widely recognized as the important metallic biomaterials. Here, the first development of CoCrMoFeMnW and CoCrMoFeMnWAg high-entropy alloys (HEAs) based on CoCrMo metallic biomaterials is reported. Ingots of six-component Co 2.6 Cr 1.2 Mo 0.2 FeMnW 0.27 (Co 41.5 Cr 19.1 Mo 3.2 Fe 16 Mn 16 W 4.3 , at%) HEAs with a minor • phase and of sevencomponent Co 4.

“…HEAs are defined as alloys comprising more than five main elements mixed in an equiatomic or near-equiatomic fraction [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. Many HEAs have been reported to have: superior mechanical properties, such as ultrahigh fracture even at high temperatures, high hardness, toughness exceeding that of most pure metals and alloys, excellent comparable strength to that of structural ceramics and some metallic glasses, exceptional ductility, and fracture toughness at cryogenic temperatures [1,3], and good physical properties, such as superconductivity, supermagnetism, and significant resistance to corrosion [5].…”

A wide variety of metallic biomaterials have been developed so far, including various types of alloys. However, there is a strong need in the medical field for new solutions in what concerns metallic biomaterials with superior biocompatibility and mechanical properties in order to meet future requirements, including the recently developed high entropy alloys (HEAs). This chapter presents some characteristics of high entropy biocompatible metallic alloys produced in an electric-arc remelting furnace in argon inert atmosphere. The effects of the chemical elements used, the microstructural features, and some mechanical characteristics, both in the cast state or after some heat treatments, are highlighted.
