Preparation method of medical iron-based non-crystal material

The invention relates to a preparation method of a medical iron-based non-crystal material and belongs to a non-crystal alloy based on iron as a main component. The preparation method comprises the following steps of: calculating and preparing required raw materials according to atom percentage at.% of various elements in target alloy (Fe75Si10B15)98Nb2: iron particles, silicon particles, boron particles and niobium particles, wherein the mass percentage of the purities of all the raw materials is 99.99%; placing all the raw materials in a vacuum arc furnace, and melting under the protection of high-purity argon to obtain Fe-Si-B-Nb alloy ingot; and then carrying out blow casting on melted Fe-Si-B-Nb alloy in a vacuum melt-spun machine to form a (Fe75Si10B15)98Nb2 non-crystal alloy strip serving as the medical iron-based non-crystal material. The preparation method disclosed by the invention overcomes the defects that the preparation process by using the existing titanium alloy as a biological ...
