Abstract

The invention provides a low-cost zirconium-based amorphous alloy which can be repeatedly used and a preparation method thereof. The zirconium-based amorphous alloy comprises the component of (ZraCubNicAldTie)100-xOx, wherein a, b, c, d, e and x all refer to atomic percent; a is not less than 40 and not greater than 60, b is not less than 34 and not greater than 50, c is not less than 0 and not greater than 5, d is not less than 2 and not greater than 14, e is not less than 0 and not greater than 5, and x is not less than 50 ppm and not greater than 5000 ppm. The zirconium-based amorphous alloy has good mechanical property and relatively high amorphous forming ability; compared with a component of a traditional amorphous alloy, the zirconium-based amorphous alloy provided by the invention has the advantage that the purity requirement on true raw material metal is lowered, so that raw material cost is reduced, and possibility is provided for industrial production.

Description

technical field [0001] The invention relates to an amorphous alloy, and in particular provides a zirconium-based amorphous alloy with relatively high amorphous forming ability and a preparation method thereof. Background technique [0002] Amorphous alloys were first discovered in the Au-Si eutectic system in the 1960s. Since then, this material has been widely concerned due to its various excellent properties, and it is considered to lead the next material revolution. . Due to the characteristics of long-range disorder and short-range order in the structure of amorphous alloys, it has unique properties compared with traditional crystalline metal materials: for example, the strength of general Zr-based amorphous alloys is twice that of steel, and its corrosion resistance It is dozens or even hundreds of times that of stainless steel, and its elastic limit of up to 2% is three times that of ordinary traditional crystal metal materials. These excellent properties have brough...
