FIELD: metallurgy; biomedical high-entropy alloy.
SUBSTANCE: biomedical high-entropy alloy for medical implants is manufactured by vacuum-arc remelting and contains high-purity chemical elements in the following percentage, at.%: titanium 30, zirconium 38, niobium 20, tantalum 8, tin 4. The alloy is characterized by ultimate strength of 1020–990 MPa, yield strength of 20–751 MPa and ductility in tension of 9–13% at room temperature.
EFFECT: can be used in medical implants due to the excellent combination of strength and ductility and the good reproducibility of these characteristics.
