Abstract
The invention discloses an alloy, especially a high-strength low-modulus bio-medical titanium alloy. The alloy is characterized in that the alloy consists of Ti, Nb, and Zr, wherein the content of the components is as follows (by weight): Nb:31-34%, Zr:6-9%, Ti: the rest. Compared to conventional technology, the alloy provided by the invention has the following advantages: 1. good biocompatibility; 2. high alloy strength(-1050MPa); 3. elastic modulus 25-30% less than Ti#-[6]Al#-[4]V; 4. excellent fatigue strength and fracture toughness; 5. good technological formability.
Description
Technical field:
The present invention relates to a kind of alloy material, particularly a kind of high-strength low-modulus bio-medical titanium.
Background technology:
Most widely used clinically at present general surgery is metal material embedded to mainly contain three kinds of stainless steels, cobalt base alloy, titanium alloy.Titanium alloy is as emerging metallic substance, advantages such as, solidity to corrosion strong, good biocompatibility with its height ratio, and it is powerful to substitute the demand growth of implanting product as the human body hard tissue reparation.But the titanium alloy kind that can provide for medical circle seldom at present, what the use of prison bed was maximum is to transplant the Ti6Al4V alloy of coming from aircraft industry, this alloy is owing to contain vanadium metal, its toxicity is generally acknowledged by medical circle, the technological forming of this alloy is bad in addition, brings difficulty for the moulding, mechanical workout etc. of the press working of material and product.
Summary of the invention:
The purpose of this invention is to provide a kind of nontoxic, high and low modulus of intensity, anti-corrosion, good biocompatibility, easy a kind of high-strength low-modulus bio-medical titanium of machine-shaping, overcome the deficiencies in the prior art.
Technical solution of the present invention is: a kind of high-strength low-modulus bio-medical titanium is characterized in that: it is made up of titanium (Ti), niobium (Nb), zirconium (Zr), and each set of dispense is such as following:
The title weight percent
Niobium (Nb) (31～34) %
Zirconium (Zr) (6～9) %
Titanium (Ti) surplus.
Described each set of dispense ratio can be:
The title weight percent
Niobium (Nb) (32～33) %
Zirconium (Zr) (7～8) %
Titanium (Ti) surplus.
The present invention compared with prior art has following advantage: 1, do not contain the toxicity constituent element, biocompatibility is good; 2, the alloy strength height (～1050Mpa) and can in a big way, adjust to satisfy the needs of dissimilar products; 3, modular ratio Ti6Al4V alloy low (25～30) %; 4, fatigue strength and fracture toughness property all are better than the Ti6Al4V alloy; 5, technological forming is good, and unit elongation exceeds 20% than Ti6Al4V alloy, and rate of compression exceeds 30% than Ti6Al4V alloy, hot processing temperature low (100 ℃～150 ℃).
Alloy bar material mechanical property of the present invention and with the comparison of existing alloy
