Abstract

A regulation Ti 48 Zr 20 Nb 12 Cu 5 be 15 The method for the thermal stability of the amorphous composite material is to realize the adjustment and control of the thermal stability of the Ti48Zr20Nb12Cu5Be15 amorphous composite material through low-temperature cold treatment. Ti 48 Zr 20 Nb 12 Cu 5 be 15 Put the sample of amorphous composite material into the cold treatment device, put the cold treatment device into the liquid nitrogen tank, so that the liquid nitrogen completely immerses the Ti in the quartz glass tube. 48 Zr 20 Nb 12 Cu 5 be 15 For amorphous composite samples, start timing when the thermometer reading reaches 77K, soak for 1 minute to 1 week, take it out and let it stand at room temperature. The present invention improves Ti 48 Zr 20 Nb 12 Cu 5 be 15 In addition to the thermal stability and aging resistance of amorphous composite materials, it also provides low-temperature atomic relaxation conditions to transform the amorphous state from one metastable state to another metastable state with lower energy, improving its compressive plasticity and making it It has more excellent comprehensive mechanical properties.

Description

technical field [0001] The content of the present invention relates to a process regulation method for thermal stability and mechanical properties of titanium-based amorphous composite materials, which belongs to the technical field of material preparation process. Background technique [0002] Amorphous alloys have long-range disorder and short-range and short-range order structures, and 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. Forming, etc., has been a research hotspot in the field of materials in the past 20 years. However, since the amorphous alloy is in a metastable state of energy in thermodynamics, there is a possibility of spontaneous transformation into a crystalline state in the direction of energy reduction under certain conditions, which is physically called amorphous crystallization, that is, at a higher tempe...
