Beta-Ti-type Ti-30Nb-10Ta-5Zr (TNTZ) wires with high-ductility were developed using the Arc-melt type melt-extraction method. The continuous melt-extracted wire with very smooth surface and small fluctuations in the diameter realizes the high tensile strength and superior bending ductility of TNTZ alloy. Figure 1 is a demonstration of the high tensile strength, ductility, and easy handling of one of the TNTZ melt-extracted wires. The TNTZ wire did not get fractured when it was used to lift a heavy load of approximately 1L water. The TNTZ wire can be bent through 180 degree without fracture in spite of the heavy load as shown in the close-up image. The wire was not damaged even when it was held tightly by a pair of needle-nose pliers. Furthermore, the OM and SEM images of the knot formed by the TNTZ wire highlight the full ductility of the wire. The Arc-melt type melt-extraction method is very effective for developing new Beta-Ti-based biomaterials [1,2].~
