Problems solved by technology

Applying this treatment state generally to the rods of this alloy will lead to the difficulty of how to make the rods uniformly pre-deformed as a whole, so the practical application of this alloy rod as 33GPa is impossible

Embodiment 1

[0027] The commercially available titanium plate, zirconium plate and titanium-niobium intermediate alloy plate are prepared into consumable electrode blocks according to the composition ratio (atomic percentage, the same below) in Table 1. The electrode blocks are welded into vacuum consumable electrodes in a vacuum plasma box , And then two vacuum consumable smelting to produce ingots (button ingots). The ingot is billeted and forged at the phase transition point. After intermediate forging, a Φ35mm rolled bar is produced. After the bar is heated to 900°C, it is rolled on a horizontal rolling mill to form a Φ15mm bar. The rolled bars are annealed at 900°C for 30 minutes and then tested for tensile properties according to GB228-2002 and tested for compression modulus of elasticity according to ASTME9-89a. The performance is shown in Table 2. The data in the table are the test results of three samples average value.

Embodiment 2

[0034] Prepare consumable electrode blocks with the composition ratios of commercially available titanium plates, zirconium plates, tantalum plates, and titanium-niobium intermediate alloy plates in Table 3. The electrode blocks are welded into a vacuum consumable electrode in a vacuum plasma box, and then two Sub-vacuum consumable melting is made into ingots (button ingots). The ingot is billeted and forged at the phase transition point. After intermediate forging, a Φ35mm rolled bar is produced. After the bar is heated to 900°C, it is rolled on a horizontal rolling mill to form a Φ15mm bar. The rolled bar is annealed at 900℃ for 30 minutes and then tested for tensile properties according to GB228-2002, and tested for compressive elastic modulus according to ASTM E9-89a. The performance is shown in Table 4, and the data in the table are three sample tests. The average of the results.

Abstract

The invention relates to biological medical titanium alloy with low elastic modulus, which comprises a Beta stable element and a neutral element. The Beta stable element is Nb or Nb and Ta. The neutral element is Zr, or Zr and Hf or Zr and Sn. Bo of the biological medical titanium alloy is within 2.882 to 20887, and Md is within 2.460 to 2.463; in the biological medical titanium alloy, the atom percent of Nb is within 25 to 27%, the atom percent of Ta is within 0 to 0.5%, the atom percent of Zr is within 3 to 5%, the atom percent of Hf or Sn is within 0 to 2%, and the rest is titanium. The tensile strength of alloy in the solid solution state at the room temperature is not lower than 600MPa, and the compressed elastic modulus is not higher than 45GPa.

Description

Technical field [0001] The invention relates to a biomedical titanium alloy with low elastic modulus. Background technique [0002] At present, the main metal materials that can be used in the medical field are stainless steel, cobalt-chromium alloys, titanium and titanium alloys. See Table 1 for the characteristics of these three types of materials as biological materials. It can be seen from the table that, except for the wear resistance and processing performance lower than the other two types of materials, the other properties are titanium and titanium alloys. Medical practice has proved that all types of surgical implants made of stainless steel and cobalt-chromium alloys can be made of titanium and titanium alloys. Long-term medical practice has shown that if the elastic modulus of the artificial joint prosthesis is much higher than the elastic modulus of the bone tissue by 10-30 GPa, the artificial joint prosthesis will bear most of the biological stress, making it diffic...
