TI ALLOY HAVING LINEAR ELASTIC DEFORMATION AND SUPER HIGH STRENGTH AND ULTRA-LOW ELASTICITY CHARACTERISTICS, CAPABLE OF MINIMIZING A STRESS SHIELDING PHENOMENA, OBTAIN EXCELLENT FORMABILITY, AND LINEARLY TRANSFORMING BY PROVIDING A TI BIOMATERIAL OF LOW YOUNG'S MODULUS

摘要

PURPOSE: A Ti alloy having linear elastic deformation and super high strength and ultra-low elasticity characteristics is provided to prevent the non-uniformity of a Ta composition generated in a massive meltage or coagulation by not adding Ta in correspondence to an element having a high melting point and to cold-form the Ti alloy over 90% at room temperature.;CONSTITUTION: A Ti alloy having linear elastic deformation comprises 19-21 mol% of Nb, 4-6 mol% of Zr, 0.5-1.5 mol% of Fe, 0.1-0.5 wt% of O, and the rest comprising Ti. The Young's modulus of the Ti alloy is 68 before a cold-forming process and 60 after the cold-forming process.;COPYRIGHT KIPO 2013
