Description
Technical field
A kind of surgery implantation piece beta titanium alloy, relate to a kind of surgery implantation metal alloy compositions, be particularly related to a kind of human body hard tissue reparation and alternate surgery medical embedded material of serving as, as the surgery implantation piece beta titanium alloy of bone, tooth, joint, splenial bone plate and intramedullary needle etc.
Background technology
Titanium alloy with its higher specific tenacity, lower Young's modulus, corrosion-resistant, biocompatibility is good and become ideal bio-medical material after traditional stainless steel and cobalt base alloy.Medical stainless steel and cobalt base alloy are owing to containing toxic element and the more high reasons of Young's modulus such as nickel, cobalt Co, chromium Cr, and clinical application reduces day by day.As far back as the beginning of the forties in last century, pure titanium just is introduced in biomedical sector, subsequently because clinical needs, alpha titanium alloy Ti3Al2.5V and alpha and beta type titan alloy Ti-6Al-4V, Ti6Al7Nb and Ti5Al2.5Fe etc. successively by people's research, development and application in the surgery implantation piece.But, above-mentioned titanium alloy also generally contains elements such as V, the Al of toxic side effect and Fe, and their Young's modulus is compared with natural bone (1-30GPa) and is still had big gap, be easy to generate " stress shielding ", thereby cause bone resorption occurring around the implant, finally cause the loosening or fracture of planting body and cause the plantation failure.Therefore, research and development biocompatibility better (adding Zr, Mo, nontoxic elements such as Nb, Sn), lower, the better medical titanium alloy of over-all properties of Young's modulus, to adapt to clinical demand to the implantation piece material, become the main direction of biomedical material research, and β type medical titanium alloy adapts to this requirement just and developed rapidly.
In recent years, a new type beta type medical titanium alloy surplus states such as U.S., day, moral have successively developed 10, as Ti-13Nb-13Zr, Ti35Nb5Ta7Zr, the Ti16Nb10Hf of the U.S., the alloys such as Ti15Mo5Zr3Al, Ti29Nb13Ta5Zr of Japan.But in these alloys, Young's modulus that has higher (90-100GPa) or Young's modulus are low to moderate 55GPa, but the not enough 600MPa of strength of alloy this moment, as the Ti35Nb5Ta7Zr alloy; The alloy unit elongation that has is lower; The alloy that has contains toxic element Al, as Ti15Mo5Zr3Al.In addition, above-mentioned alloy since heavy addition rare expensive refractory metal Hf, Ta, Mo, Nb, make that the ingot metallurgy quality is wayward, need to increase melting number of times and corresponding raw material and tooling cost.In general, be used for the titanium alloy material of organism, except satisfying excellent biological compatibility and solidity to corrosion, also should have medium above intensity (σ
b: 650-1000MPa), suitable plasticity (δ
s: 6%-28%), lower Young's modulus (50-85GPa) and relatively low cost.
Summary of the invention
The objective of the invention is the deficiency that exists in above-mentioned prior art, the surgery implantation piece that a kind of Young's modulus is lower, intensity is higher, plasticity is better, cost is relatively low beta titanium alloy is provided.
The objective of the invention is to be achieved through the following technical solutions.
A kind of surgery implantation piece beta titanium alloy is characterized in that the weight percent of its alloy consists of: zirconium 0.1%-9.5%; Tin: 0.5%-9.5%; Molybdenum: 0.5%-9.5%; Niobium: 20%-30%, surplus is titanium and unavoidable impurities, wherein low gap constituent content carbon C≤0.03%; Nitrogen N≤0.04%; Hydrogen H≤0.003%; Oxygen O≤0.12%.
Surgery implantation piece of the present invention adopts a certain proportion of, as to have good biocompatibility zirconium, niobium, molybdenum and tin element as additive with beta titanium alloy, control surgery implantation piece is 7.2-11.9 with beta titanium alloy molybdenum equivalent, makes it form the stable nearly β type medical titanium alloy that is situated between.Thereby provide the surgery implantation piece that a kind of Young's modulus is lower, intensity is higher, plasticity is better, cost is relatively low beta titanium alloy.
The normal calculation formula of relevant molybdenum is as follows:
〔Mo〕eq＝％〔Mo〕+％〔V/1.5〕+〔W〕/2+％〔Nb〕/3.6+％〔Ta〕/4.5+％〔Fe〕/0.35+％〔Cr〕/0.63+％〔Mn〕/0.65+％〔Ni〕/0.8-％〔Al〕
Above-mentioned design reasons is: Mo, Nb, Zr, Sn help alloy strengthening; Nb, Zr, Mo element are beneficial to the reduction Young's modulus; Zr, Sn, Nb element are little to the plasticity disadvantageous effect, even improve alloy plasticity; The Mo crystal grain thinning can improve the hot and cold plasticity of alloy; Nb is also favourable to improving toughness.But it is excessive that Mo, Nb element add, and increases the stable degree of alloy first, alloy solid solution aging effect is subsequently weakened or loses and can't realize alloy structure and performance adjustment; Second increase alloy density and raw material and melting tooling cost thereof, and be easy to occur the composition segregation during melting and tissue odds is even.For example to disclose a kind of Ti-Zr-Mo-Nb be biological titanium alloy to United States Patent (USP) (US5,871,595), and its alloy content is very high, and it forms weight ratio is Ti-Zr (10%-46%)-Mo (3%-15%)-Nb (29%-70%).And Mo, Nb, Zr, the Sn element of control suitable proportion make it form the stable nearly beta titanium alloy that is situated between, and adjust alloy property (as intensity, Young's modulus and unit elongation etc.) thereby can handle by solid solution aging; And this type of alloy easily brings out martensite in solution treatment or when loading and forms, and then causes the higher plasticity of alloy, is convenient to following process.
A kind of surgery implantation piece beta titanium alloy of the present invention, best composition scope is zirconium: 1.5%-4.5%; Tin: 0.5%-5.5%, molybdenum 1.5%-4.4%; Niobium 23.5%-26.5%, surplus is titanium and unavoidable impurities, molybdenum equivalent 7.2-11.9.
Alloy preparation process of the present invention is that refractory metal elements Mo, Nb are added with master alloy TiNb (Nb weight content 25%-55%) and TiMo (Mo weight content 10%-30%) form, or adds with Nb bar and pure Mo powder; Element Zr adds with zirconium sponge or pure zirconium strips; Element S n adds with pure Sn strips; Adopt the zero level titanium sponge with lower interstitial impurity constituent content in the control alloy substrate.Twice or three times of the melting in vacuum consumable electrode arc furnace of batching back.The ingot casting cogging is forged and to be chosen in 1000 ℃-1100 ℃ and to carry out, and selects 900 ℃-1000 ℃ to implement finished products forging or rolling etc.The solution treatment system is: temperature is controlled between-50 ℃～+ 100 ℃ of α/β transformation temperature, soaking time 0.5-1.5 hour, adopts shrend or air cooling; System of ageing treatment is: temperature is chosen in 480 ℃-640 ℃, is incubated 4-12 hour, air cooling.The performance data of its tensile strength, yield strength, unit elongation, reduction of area and Young's modulus and over-all properties all are better than advanced in the world at present medical beta titanium alloy, as Ti-13Nb-13Zr, Ti35Nb5Ta7Zr, the Ti16Nb10Hf of the U.S., the alloys such as Ti15Mo5Zr3Al, Ti29Nb13Ta5Zr of Japan.
