Abstract

The invention discloses a metastable beta-type Ti-Mo-Si system biomedical alloy and a preparation method thereof. The metastable beta-type Ti-Mo-Si system biomedical alloy comprises the following raw material components in percentage by weight: 88.00-90.00 percent of sponge titanium, 0.00-2.00 percent of silicon and 9.5-10.50 percent of molybdenum. The preparation method comprises the following steps of: firstly, respectively weighing raw material according to the weight percentage of the raw material components; secondly, uniformly mixing the raw materials and melting the raw materials by using non-consumable arc; and finally, cooling to obtain an alloy cast ingot with a uniform structure. According to the metastable beta-type Ti-Mo-Si system biomedical alloy and the preparation method thereof disclosed by the invention, the non-poisonous molybdenum and low-price silicon are added to improve the phase composition and the mechanical property of a titanium alloy, so that the mechanical property of the alloy is better matched with that of natural bone of a human body. The low-price silicon is used as one of alloying elements, so that the production cost of the alloy is effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of titanium alloys, in particular to metastable β-type biomedical titanium alloys. Background technique [0002] Biomedical materials include materials that can be medically implanted into organisms or combined with biological tissues. Biomaterials are used to treat or replace original tissues and organs in biological organisms, and to correct and improve their functions. At present, biomedical metal materials are widely used as surgical implant materials. They have high strength, good toughness, bending fatigue resistance and good processing and forming properties, and have excellent properties that other types of medical materials cannot replace. As biomedical materials, metal materials must meet strict biological requirements: (1) good tissue compatibility, non-toxicity, no distortion, no allergic reaction, no interference with the body's immunity, no damage to adjacent tissues, etc.; (2) physical and che...
