Fabrication of beta-Ti-type Ti-Nb-Ta-Zr (TNTZ) wire with high-ductility by arc-melt-type melt-extraction method

Abstract

Beta-Ti-type Ti-30Nb-10Ta-5Zr (TNTZ) wires with high-ductility were developed using the arc-melt-type melt-extraction mediod. 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. The melt-extracted Beta-Ti wire shows the possibility for the use in biomedical applications. The arc-melt-type melt-extraction method is very effective for developing new Beta-Ti-based biomatenals © 2010 The Japan Institute of Metals.
