Embodiment

[0030] The formulation of the zirconium-based amorphous alloy in the present invention is proportioned according to the ingredients in the following table, and the numbers after the element symbols are the atomic percentages of each element.

[0031]

[0032] Alloy preparation method:

[0033] Step 1, the zirconium-based amorphous alloy raw materials are mixed according to the formula, and the purity of the raw materials is greater than 99.9%.

[0034] In Examples 1-10, the Be element is added in the form of NiBeM master alloy, wherein the atomic percentage of Ni, Be, and M is 1:3:0.6, and the rest of the raw materials are added in the form of powder. (The atomic percentages of Ni and Be that do not contain the M component remain unchanged).

[0035] In Examples 11-18, the Be element is added in the form of TiBeM master alloy, wherein the atomic percentage of Ti, Be, and M is 1:4.5:0.6, and the remaining raw materials are added in the form of powder. (The atomic percentag...

Abstract

The invention discloses a low-brittleness zirconium-based amorphous alloy. The zirconium-based amorphous alloy has the composition of (ZraTibCucNidBeeMfNg)1-xOx, wherein M is one or more of Ag, In andSb, and N is one or more of Mo, Mn and Pr; a, b, c, d, e, f, g and x represent atomic percentages, 39<=a<=44, 10<=b<=15, 10<=c<=14, 6<=d<=15, 18<=e<=23, 0<=f<=10, 0<=g<=1, and 100 ppm<=x<=200 ppm. Through improvement in the composition and the preparation method, the zirconium-based amorphous alloy has high hardness, high tensile strength and formation size; and most importantly, the zirconium-based amorphous alloy has low brittleness, and solves the problem of large brittleness of a zirconium-based amorphous alloy in the prior art.

Description

technical field [0001] The invention belongs to the field of metal materials, and in particular relates to a low-brittle zirconium-based amorphous alloy and a preparation method thereof. Background technique [0002] Considering the atomic model that makes up matter, matter can be divided into two types: ordered structure and disordered structure. Among them, crystal is a typical ordered structure, while gas, liquid and some solids are all disordered structures. Amorphous alloys, referred to as amorphous alloys, refer to metal alloys that do not have long-range order but have short-range order. Due to the characteristics of metal alloys, amorphous alloy liquids are called glassy alloys or amorphous alloys. Amorphous alloys have long-range disorder but short-range order means that the atoms do not exhibit periodicity and translational symmetry in spatial arrangement, but there is a certain regularity in the bonding with adjacent or sub-adjacent atoms in the tiny scale of 1-2n...
