Description
Affiliated technical field
The utility model provides a kind of continuous preparation device of bulk amorphous alloys, belongs to metallurgy, material forming and preparing technical field.
Background technology
Compare with common polycrystalline metal material, amorphous alloy (being called glassy metal again) has high strength, high rigidity, high elastic limit, excellent properties such as corrosion-resistant, wear-resistant.Enter twentieth century nineties, people find that in succession some palladiums, zirconium, lanthanum alloy are 10
7Cooling can form glassy metal under the speed of K/ second-time.Adopt common foundry engieering just can obtain the glassy metal block materials, encouraging prospects have been showed in the application of glassy metal.In in the past 10 years, the research of block metal glass has caused numerous scientists' interest in the world, and new achievement in research is not emerged in large numbers absolutely.Developing low cost, being easy to cast the novel alloy that becomes the blocks of large material is target of greatest concern all the time, also is the key that has the final practicability intellectual property of material simultaneously.
1991, Akihisa Inoue seminar of northeastern Japan university adopted 4 millimeters " magnesium-copper-yttrium " ternary alloy three-partalloy glass of copper mold casting forming diameter pole.June nineteen ninety-five, the Korea S scientist prepared the magnesium alloy glass that diameter reaches 14 millimeters (see J.Mater.Res.vol.20,2005, p.1465).The fracture strength of magnesium-base metal glass can reach the 800-900 MPa, is 2 ~ 3 times of common commercial magnesium alloy.Metal research Shenyang material science country (associating) of Chinese Academy of Sciences laboratory development goes out magnesium alloy Mg

30The critical non-crystaline amorphous metal size that alloy obtains can reach diameter 30mm (Mater.Trans.JlM, 1996 (37), P181).At present, the amorphous alloy of the relative low price that some glass forming abilities are very strong is seen in report in succession.For example zirconium base, the critical amorphous size of magnesium base alloy can reach more than the 10mm, and critical cooling rate has been reduced to 10～100K/s.
The main method of laboratory bulk amorphous alloy preparation has: die cast, wedge-shaped die casting, negative pressure casting (suction pouring), casting forming, shrend, directional solidification, jet are shaped or the like.
The preparation of disclosed bulk amorphous alloys has in patented technology at present: granted patent CN99250780.4 has introduced vacuum pressure casting bulk amorphous alloys device, utilizes gas pressure that the alloy of fusing is cast at a high speed in the copper film, forms bulk amorphous alloys; Granted patent CN02111709.8 has introduced and has utilized cyclone that the zirconium-base alloy of fusing is separated into fine drop, and the droplets fall process is at first pre-cooled by inert gas, enters in the condenser (casting mold) that is forced to cool off again and finishes the preparation method of solidifying; Patent CN03121418.5 has introduced and has utilized gas pressure to spray and negative pressure of vacuum suction casting measure, the alloy that melts is injected water cooled copper mould at a high speed obtain non-crystal method and apparatus; The method that patent CN03128762.X introduces is, alloy liquid is poured into form in the slit of a water-cooled roll noncrystal.
The common ground of these technology is, alloy liquid is cooled and solidified in casting mold (copper mold, roll etc.), and alloy liquid contacts closely with the casting mold wall.According to classical liquid alloy crystallization theory, it is the process that a nucleus forms, grows up that liquid alloy is solidified as crystal, and the wall of cooling casting mold can promote the formation of nucleus well and grow up, and is unfavorable for that alloy transforms to amorphous.Secondly, be seen in the reported method, except the method that patent CN03121418.5 introduces, the size of non-crystaline amorphous metal is subjected to the limitation of casting mold three-dimensional dimension.
