Embodiment Construction

[0026] The experimental methods in the following examples are conventional methods unless otherwise specified, and the involved experimental reagents and materials are conventional biochemical reagents and materials unless otherwise specified.

[0027] Invented and realized a brand-new main component design theory and impurity control method of TC4ELI titanium alloy within the scope of domestic and foreign standards: master alloy manufacturing method to prevent micro-segregation in the main component area; micro-alloy multi-component strengthening; ultra-low N, H, C impurities content and trace elements to refine the grain.

[0028] 1. Preparation of master alloy with new composition

[0029] In the traditional manufacturing process of TC4ELI titanium alloy processing materials in China, aluminum is smelted by ingot casting, and vanadium element is added by intermediate alloy method. The master alloy used for smelting ingredients is a vanadium-aluminum master alloy produced b...

Abstract

The invention belongs to the technical field of biomedical metallic materials and specifically relates to a manufacturing method for a biomedical titanium alloy TC4ELI rod/wire material. The manufacturing method for the biomedical titanium alloy TC4ELI rod/wire material specifically comprises the following steps: smelting vanadium-aluminum immediate alloy, produced by using an aluminothermic process, and realuminization in a vacuum state at a time; adding a trace amount of strengthening elements of tin and zirconium and a trace amount of refined grain element rare earth in the vacuum smeltingprocess to prepare a new component immediate alloy; mixing the new component immediate alloy and titanium sponge to form a TC4ELI titanium alloy cast ingot; and finally, preparing the TC4ELI titaniumalloy rod/wire material. The manufacturing method for the biomedical titanium alloy TC4ELI rod/wire material, provided by the invention, has the advantages that the process is stable, regional segregation caused by supplementing the elementary aluminium element to the smelted cast ingot is avoided, and the uniformity of trace elements is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of medical metal materials, and in particular relates to a method for manufacturing a biomedical titanium alloy TC4ELI rod / wire. Background technique [0002] Among biomedical metal materials, titanium and its alloys have become the most popular products for artificial joints (hip, knee, shoulder, ankle, elbow, wrist, knuckles, etc.), orthopedic trauma products (intramedullary nails, plates, screws, etc.) due to their excellent comprehensive properties. ), spinal orthopedic internal fixation systems, dental implants, dental trays, dental orthopedic wires, artificial heart valves, interventional cardiovascular stents and other medical implant products. It has high fracture toughness, low crack growth rate, low interstitial element type Ti-6A1-4VELI (domestic brand TC4ELI) and high damage tolerance titanium alloy, which is widely used and currently accounts for more than 80% of titanium alloy implant products ...
