Embodiment 1

[0029] This example is used to illustrate the preparation of the titanium-based amorphous alloy provided by the present invention.

[0030] A total of 50 grams of raw materials Ti, Cu, Ag, and Sc were put into a vacuum induction furnace according to a certain ratio, evacuated to 50 Pa, and then filled with argon (the purity of argon is 99% by volume), at about 2000 ° C , smelting for 2 minutes to fully melt the alloy raw material, and then remelt 3 times to fully alloy it;

[0031] Then the molten alloy sample is cast into a metal mold by high-pressure casting (wherein, pressure 20MPa, mold material SKD61) cooling molding (cooling speed is 102K / s), and the obtained size is 100 mm long * 10 mm wide * high 3 mm bulk Ti-based amorphous alloy sample Al. The mass fraction of elements contained in the alloy was analyzed by inductively coupled plasma emission spectroscopy (ICP-AES), and converted into atomic percentage, it can be known that the composition of the bulk titanium-based...

Description

technical field [0001] The invention relates to an amorphous alloy and a preparation method thereof, in particular to a titanium-based amorphous alloy and a preparation method thereof. Background technique [0002] Amorphous alloys are a new class of alloy materials whose constituent atoms are long-range disordered and short-range ordered. Due to its unique microstructure, it has superior mechanical, physical, chemical and other properties than conventional crystalline metal materials. [0003] Titanium-based bulk amorphous alloys have broad application prospects in new high-temperature corrosion-resistant structural materials and biomedical devices due to their extremely high fracture strength, low density, excellent room temperature corrosion resistance, and low cost. , so it has received extensive attention and research. After nearly 30 years of exploration and hard work, people have developed a large number of titanium-based amorphous alloy systems, such as: Ti-Be-Zr, ...
