Example Embodiment

[0022] Five high-purity pure metals are selected, namely Zr (99.99wt%), Ti (99.995wt%), Cu (99.95wt%), Ni (99.95wt%), Be (99.999wt%). The atomic percentage is: Zr is 40, Cu is 10, Ni is 11, Ti is 5, and Be is 25. Under the protection of argon gas with a purity of 99.8%, the purification technology of liquid master alloy is applied, and arc melting is used. The master alloy was prepared by the method. To ensure the homogeneity of the components in the master alloy, the master alloy was remelted three times. The surface of the master alloy ingot is mechanically ground and polished to remove the oxide scale on the surface, then crushed into small pieces and the surface is cleaned with alcohol. These small pieces of master alloy are broken into a graphite crucible, and the Zr shown in FIG. 2 is prepared by using the device shown in FIG. 1 and according to the working principle as described above. 40 Ti 14 Ni 11 Cu 10 Be 25bar. Using an X-ray diffractometer, the diffraction ...

Abstract

A spray casting-suction casing apparatus for preparing great non-crystal alloy block is composed of upper and lower furnace chambers, water-cooled partition between said chambers, heating body consisting of one Mo sheet layer and 6 reflecting screen layers, mould made of quartz glass or graphite arranged in said heating body and passing through said partition, U-shaped seals, plug pulling unit for the quartz glass (or graphit) plug of the circular hole on the bottom of mould, and water-cooled copper mould made of red copper.

Description

Technical field: [0001] The invention belongs to the technical field of spray-casting-suction casting of bulk amorphous alloys, and in particular provides a preparation method of vacuum spray-casting-suction casting of bulk amorphous alloys and corresponding equipment. Background technique: [0002] Bulk amorphous alloy materials are a class of advanced materials developed rapidly in the 1990s. Compared with traditional crystalline alloy materials, bulk amorphous alloys have more excellent mechanical properties, the ability to resist corrosion by various media, good soft and hard magnetic properties, and unique expansion characteristics. Bulk amorphous alloys have very attractive application prospects. In the early nineties, A.Inoue, T Zhang and T.Masumoto.Mater.Trans., JIM, 30(1989), 965 and American A.Peker and W.L.Johnson, Appl.Phys.Lett., 63(1993), 2342 breaks through the high-speed cooling (>10 6 K / s) limit, so that under the cooling rate condition that convention...
