Title:
SUPER ELASTICITY AND LOW MODULUS TI ALLOY AND ITS MANUFACTURE PROCESS
Document Type and Number:
WIPO Patent Application WO/2005/064026
Kind Code:
A1
Abstract:
The present invention concerns a Ti-Nb-Zr Ti alloy. The alloy comprises 20-35wt% Nb, 2-15wt%Zr, balance Ti and inevitable inclusions. The Ti alloy according to the present invention has several advantages as follow: the alloy has excellent cold workability and very low work hardening rate, and the alloy could be processed with high degree cold deformation by means of cold working processes such as cold rolling and cold drawing ; the alloy has the properties of super elasticity, shape memory and damp characteristics, low elastic modulus, high strength, corrosion resistance and high flesh compatibility; the alloy could be used to prepare nanometer materials with crystal grains of nano scale, and could be used to prepare nanometer materials with ultrahigh strength through heat treatment.
