Embodiment 1

[0028] [Ti a Zr b (Ni x Fe 1-x ) c be d ] 100-y Cu y In the alloy system, a=36%; b=33%; c=6%; d=25%; x=1; y=9 (denoted as ZT3, atomic percentage). The Ti and Zr in the raw materials are sponge Ti and sponge Zr with industrial purity, and the purity of other elements is higher than 99.8wt%. After a certain quality of raw materials is prepared according to the atomic percentage, the master alloy is prepared by arc melting under the protection of argon. Ingots, in order to ensure the uniformity of the smelted alloy ingots, the alloy ingots were repeatedly smelted four times. The present invention adopts water quenching casting, and the degree of vacuum is 8×10 -4 Pa, at a temperature of 1000°C, through water quenching equipment, to obtain an amorphous rod with a size of Φ50×65mm. figure 1 It is the X-ray diffraction spectrum of water-quenched ZT3 alloys with different sizes. It can be seen from the figure that the diffraction curves of ZT3 alloys with diameters of 30mm, ...

Abstract

The invention relates to the field of Ti-based amorphous alloys, in particular to a Ti-Zr-Cu-Ni(Fe)-Be alloy with extremely high glass forming capacity and a preparation method. The alloy system is Ti-Zr-Cu-Ni(Fe)-Be alloy, of which the composition range varies according to the following principle (atomic percent): the proportion mode is [TiaZrb(NixFe1-x)cBed]100-yCuy, wherein a is equal to 31-40percent; b is equal to 23-38 percent, c is equal to 0-9 percent, d is equal to 20-35 percent, x is equal to 0-1 and y is equal to 0-20. In the invention, initial alloy which can be used for developing amorphous alloy with high glass forming capacity is discovered by systematically analyzing a Ti-Zr-Cu-Ni(Fe)-Be alloy solidification structure, and has a typical solidification structure characteristic, namely the initial alloy mainly consists of an amorphous structure and a primary crystalline state structure; and a plurality of types of titanium-based amorphous alloys with extremely high glassforming capacity are successfully obtained by further optimizing the amorphous phase composition in the alloy. The titanium-based amorphous alloy with maximum size of at least more than phi 50mm is obtained by using a water quenching technology. The alloy shows superior mechanical property and has great application prospect.

Description

technical field [0001] The invention relates to the field of Ti-based amorphous alloys, in particular to a Ti-Zr-Cu-Ni(Fe)-Be alloy with extremely high amorphous forming ability and a preparation method. Background technique [0002] Ti-based amorphous has excellent mechanical properties and relatively low cost, and is one of the hotspots in the field of amorphous research. In the past few decades, scholars from various countries have conducted a lot of research on Ti-based amorphous alloys, and obtained a series of Ti-based amorphous alloys: Ti-Be-Zr, Ti-Si, Ti-Ni, Ti-Be, Ti-TM-Si, Ti-Ni-Cu and other Ti-based amorphous strips. In addition, a series of Ti-based amorphous alloys with greater glass forming ability have been developed, mainly including: Ti-Ni-Cu-Sn, Ti-Zr-Ni-Cu-Be, Ti-Zr-Ni-Cu, Ti-Zr-Ni-Cu-Hf-Si-Sn, Ti-Ni-Cu-Si-B, Ti 50 Cu 25 Ni 20 co 5 . In these alloy systems, Ti-based bulk amorphous crystals without Be can form rods with a maximum diameter of about Φ6...
