Abstract

The invention relates to the technical field of Mo alloys, in particular to a Mo-Re-T series alloy as well as a preparation method and application thereof. The Mo-Re-T series alloy comprises Re, Mo and inevitable impurities as well as further comprises T, wherein the content of T is less than that of Mo; and T is selected from at least one element of K, Al, Si, Mn, Ga, Ge, Sr, Ru, Rh, Cd, In, Sn, Ag, Ta, W, Au, Cu, Sb, Ba, Ir, Bi or rare earth. The material strength of the Mo-Re-T series alloy is remarkably improved; the mechanical and biological compatibilities between the modulus, the hardness, the abrasion resistance and the fatigue performance of the Mo-Re-T series alloy and bone tissues are better; meanwhile, the Mo-Re-T series alloy has excellent ray impermeability and low magnetic susceptibility; and the accurate tracking during radiography is further facilitated.

Description

technical field [0001] The invention relates to the technical field of molybdenum alloys, in particular to a Mo-Re-T series alloy and its preparation method and application. Background technique [0002] Metal materials are widely used in vascular stents, orthopedics and heart valves because of their good mechanical properties. Medical stainless steel, cobalt-based alloys and titanium alloys are the three major series of medical metal materials for surgical implants and orthopedic devices. Titanium and titanium alloy materials are currently the most widely used implant metals. They have excellent mechanical properties such as low density, high specific strength, and elastic modulus similar to bone, and are non-toxic, good biocompatibility, corrosion resistance and The anti-fatigue performance is obviously better than other medical metals, so it has been more and more widely used clinically. However, there are still many problems to be improved in the existing medical metal...
