Abstract A novel equiatomic TiNbTaZrMo high-entropy alloy (HEA) was developed as a new metallic biomaterial. The constituent elements of the HEA were biocomparable, and the HEA was designed based on parameters such as the mixing enthalpy (Δ H mix ), the omega parameter ( Ω ), the delta parameter ( δ ), and the valence electron concentration (VEC) theory. The bcc solid solution phases with the different lattice constants were obtained in as-cast and annealed states. The HEA showed considerable strength with deformability and superior biocompatibility comparable to pure Ti. This study demonstrated the possibility of using HEAs as a new class of metallic biomaterials.
