Abstract

The invention relates to a zirconium-based amorphous alloy. The amorphous alloy contains Zr, Ti, Cu, Ni, Fe and Be, wherein the amorphous alloy also contains Sn and selectively contains ETM and LTM. The ETM can be one or several of elements of IIIB family, IVB family, VB family and VIB family in the periodic table of elements except zirconium and titanium. The LTM can be one or several of elements of IB family, IIB family, VIIB family and VIII family in the periodic table of elements except copper, nickel and iron. The adding of the tin element into the zirconium-based amorphous alloy can effectively improve the amorphous forming capacity of the material. The critical dimension of the amorphous alloy can reach a centimeter level. Simultaneously, due to good plasticity of the alloy, the alloy can avoid sudden failure when bearing load and improve the applicability of the material.

Description

technical field [0001] The invention relates to a zirconium-based amorphous alloy and a preparation method thereof. Background technique [0002] Amorphous metal alloys have excellent physical and chemical properties due to their special structure - long-range disorder and short-range order: high strength, high hardness, wear resistance, corrosion resistance, large elastic limit and high electrical resistance etc. In addition, it also exhibits excellent superconductivity and low magnetic loss. Therefore, amorphous metal materials have become recognized as the most potential new structural materials, and are widely used in many fields such as machinery, IT electronics, and military industry. The emergence of bulk amorphous metal materials has greatly promoted the research and application of amorphous materials. [0003] However, some properties of the amorphous material limit its application. The problems that urgently need to be solved under the existing technical conditi...
