Abstract

The invention discloses a method of regulating the thermostability of a Ti48Zr20Nb12Cu5Be15 amorphous composite though low temperature cold treatment. A Ti48Zr20Nb12Cu5Be15 amorphous composite sample is put in a cold treatment device; the cold treatment device is put in a liquid nitrogen container to allow the Ti48Zr20Nb12Cu5Be15 amorphous composite sample in a quartz glass tube to be completely soaked in liquid nitrogen; when an indicator of a thermometer reaches 77K, the timing begins; and after being soaked for 1min to 1 week, the Ti48Zr20Nb12Cu5Be15 amorphous composite sample is taken out and stands at room temperature. The thermostability and aging resistance of the Ti48Zr20Nb12Cu5Be15 amorphous composite are improved. In addition, a low temperature atom relaxation condition is provided, so that the Ti48Zr20Nb12Cu5Be15 amorphous composite in a metastable state is turned to another Ti48Zr20Nb12Cu5Be15 amorphous composite in a metastable state having lower energy, the compressive plasticity of the Ti48Zr20Nb12Cu5Be15 amorphous composite is improved, and the Ti48Zr20Nb12Cu5Be15 amorphous composite 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...
