Abstract
The present invention discloses an alloy, particularly a high-strength low-modulus biological and medical titanium alloy. The present invention is characterized in that the alloy is prepared from 31% to 34% of niobium (Nb), 6% to 9% of zirconium (Zr) and titanium (Ti) as the rest. Compared with the prior art, the alloy of the present invention has the following advantages that the alloy has no toxic element and good biocompatibility; the strength of the alloy is high (1050MPa) and can be regulated within a large range in order to meet the requirements of different types of products; the elastic modulus ratio of the ally is lower than that of a Ti6Al4V alloy by 25% to 30%; the fatigue strength and the fracture toughness are superior to those of the Ti6Al4V alloy; the alloy has good process compactibility, compared with the Ti6Al4V alloy, the elongation rate is increased by 20%, the compression rate is increased by 30%, and the hot-processing temperature is low (100 DEG C to 150 DEG C).
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,
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
