Problems solved by technology

[0003] The mechanical strength of the current metal alloy materials is generally below 1000 MPa, and the zirconium-based bulk amorphous alloy material is above 1500 MPa, and its mechanical strength is much better than that of traditional metal alloy materials; however, the current reported zirconium-based bulk amorphous alloy materials The toughness is much lower than that of metal alloy materials, which causes the reliability test failure of the actual product in the application
The improvement of the toughness of Zr-based amorphous alloys has always been a bottleneck problem in the industry, and no significant improvement has been reported so far.

[0057] 1. According to the formula of chemical composition (Zr 0.9889 f 0.011 ) 55 (Cu 1-b-c-d Ni 0.1 al 0.22 Y 0.01 ) 40 Nb 3.5 Fe 1.5 , converted into atomic molar ratio is shown in the table below. Each formula needs to prepare 240g master alloy, one master alloy is prepared according to 60g, and a total of 4 master alloys need to be prepared. Convert to desired weighing weight according to atomic mass (total weight is 60 grams, 4 parts). Among them, the purity of zirconium is 99.4%, which is industrial-grade sponge zirconium, and the purity of other elements is 99.9%. The Hf element can also choose sponge zirconium with a certain Hf content, and the weight needs to be converted according to the atomic percentage.

Abstract

The invention involves high -mechanical properties in the field of materials, and specially involves a high -tough high -intensity illegal alloy and its preparation methods.The chemical composition of the alloy is: (ZR a HF 1‑a Cure x (CU 1‑b‑c‑d NI b AL c L d Cure y NB z M 100‑x‑y‑z ; Based on the ingredients of the original ZR -based amorphous alloy excellent performance, the present invention adds a specific element that can increase the illegal chaos, improve its glass formation ability and mechanicality.In the following, it has improved its curvature breaks. The method provided by the present invention does not require additional processes. It does not need to be complicated to the alloy raw materials, nor the surface treatment of the products after the molding.

Description

technical field [0001] The invention relates to materials with high mechanical properties in the fields of consumer electronics, precision devices (such as robots), medical equipment, and aerospace, and in particular to a high-toughness ultra-high-strength zirconium-based amorphous alloy and a preparation method thereof. Background technique [0002] Amorphous alloys are named for their obvious structural differences from common crystalline materials. General materials exist in the form of crystals, and the characteristics of amorphous are long-range disorder (short-range order), metastable state (crystallization at a certain temperature), isotropic physical properties to a certain extent, no exact melting point, and glass transition temperature, etc. At the same time, because it has a similar structure to common glass, it has the characteristics of solid state, metal, and glass, so it is also called metallic glass (Metallic Glass). Because of its biggest structural featur...
