Problems solved by technology

Although the above scheme is simple in process and does not require investment in special equipment, it does not have the same effect on all zirconium-based amorphous alloys. At the same time, there are many process steps to control its smelting, and the consumption of manpower and material resources is also large.

Embodiment

[0029] The formula of the amorphous alloy in the present invention is proportioned according to the ingredients in the following table, and the number after the element symbol is the mole percentage of each element.

[0030]

[0031]

[0032] Alloy preparation method:

[0033] Step 1: Mix the amorphous alloy raw materials with purity greater than 99.99% according to the formula, stir and mix them evenly;

[0034] Step 2: Melt the mixed raw materials in a vacuum or argon atmosphere by arc melting or other conventional melting methods, and the melting is repeated 3 times; the vacuum degree of the melting process is 10 -3 Pa, or the pressure of argon atmosphere is 0.01MPa, the amorphous alloy ingot is obtained after cooling; the melting temperature is 140℃ higher than the melting point of the amorphous alloy in the formula; the cooling rate of the amorphous ingot after melting is 6×10 3 K / s;

[0035] Step 3: After crushing the amorphous alloy ingot obtained in step 2, it is smelted again ...

Abstract

The invention discloses a high-tenacity and high-plasticity amorphous alloy. The high-tenacity and high-plasticity amorphous alloy is characterized in that according to the element composition and the atom mole percentage of the amorphous alloy, Zr accounts for 50% to 60%, Al accounts for 10% to 16%, a component M1 accounts for 26% to 30%, and a component M2 accounts for 2% to 5%; the component M1 includes two elements in Cu, Co, Ni, Fe, Ti, Sc, Mn and Mo, wherein the atom mole percentage of one single element is not lower than 12%; and the component M2 includes one of Y, Ag, Nb, Ta and Hf. The amorphous alloy can be applied as a high-tenacity and high-plasticity material, for example, the amorphous alloy is applied to consumer electronic products, automobiles, medical apparatus and instrument products, the jewelry industry, the stationery industry and the aerospace industry.

Description

Technical field [0001] The invention relates to an amorphous alloy, in particular to an amorphous alloy with good toughness and plasticity, a preparation method of the amorphous alloy, and application of the amorphous alloy. Background technique [0002] Amorphous alloys, referred to as amorphous alloys, are metal functional materials with new microstructures that have only appeared in the past 30 years. Amorphous alloys are multi-element alloy systems like crystalline alloys. However, unlike the periodic arrangement of atoms in crystalline alloys, the arrangement of atoms in amorphous alloys does not have the characteristics of long-range order. And only in the vicinity of a single atom has a certain degree of short-range order. Because amorphous alloys have special structural characteristics and do not have defects such as grain boundaries, dislocations and twins of traditional crystalline materials, they exhibit many peculiar properties that exceed the corresponding crystalli...
