Abstract

Disclosed is a method for regulating the micro structure of a Ti-Zr-Nb-Cu-Be-system amorphous composite material. A high-melting-point molybdenum wire is used for carrying out hanging and overheating treatment, and the original thick structure of the Ti-based morphous composite material is completed removed in the melt treatment process. Meanwhile, the alloy melt can be purified through overheating treatment, a higher super-cooling degree can be obtained in the condensation process, the nucleation rate is sharply increased, and therefore a thorough second refined phase can be obtained.

Description

technical field [0001] The invention relates to a process control method for the microstructure of a titanium-based amorphous composite material, and belongs to the technical field of material preparation process. Background technique [0002] Amorphous alloys have a structure of long-range disorder and medium-short-range order, so they have many unique properties different from traditional crystalline alloys, such as high strength, high hardness, good wear resistance and corrosion resistance, and easy near-net shape processing. Therefore, it has become a research hotspot in the field of materials in the past 20 years. Compared with other amorphous alloys, titanium-based amorphous alloys have the characteristics of low cost, high specific strength and moderate Young's modulus, so they have attracted more and more attention and become a potential lightweight structural material. However, due to the lack of deformation mechanisms such as dislocation slip and twinning, the def...
