Description
Technical field
The invention belongs to amorphous composite preparing technical field, a kind of melting and casting method and special casting device thereof of titanium-based amorphous matrix material is particularly provided.
Background technology
Non-crystaline amorphous metal is because its special long-range is unordered, the atomic structure of short range order, show the performance more excellent than traditional crystal alloy, such as the superplasticity in high strength, high rigidity, high anti-corrosion, excellent magnetic performance and certain temperature range etc., demonstrate huge using value in fields such as aerospace device, precision optical machinery and information.But because non-crystaline amorphous metal temperature-room type plasticity is poor, critical size is little, make the widespread use of non-crystaline amorphous metal be subject to larger restriction.Utilize the titanium-based amorphous matrix material that spontaneous complex method obtains to there is excellent low temperature, room temperature and mechanical behavior under high temperature, possessed the great potential of practical application.The conventional method of preparing amorphous and amorphous composite has arc melting+copper mold now; Induction melting+spray to cast; Quartz tube water quenching methods etc., every kind of method all has certain feature, also has certain limitation and shortcoming simultaneously.The amorphous composite size preparing by these methods is less, and cannot monitor accurately the design parameter in melting and casting process, dependence and operator's experience to a certain extent, thereby in performance, be unsettled.Relation between analysis process-tissue-performance theoretically for this reason, and then realize the Reasonable Regulation And Control to wild phase size and pattern by controlling processing parameter, the large size amorphous composite that obtains rock steady structure has realistic meaning clearly.
Traditional amorphous and matrix material thereof be prepared with arc melting+copper mold (Inoue, A.and T.Zhang (1995). " Fabrication of bulky Zr-based glassy alloys by suction casting into copper mold. " Materials transactions-JIM36:1184-1187.), induction melting spray to cast (K ü hn, U., J.Eckert, et al. (2002). " ZrNbCuNiAl bulk metallic glass matrix composites containing dendritic bcc phase precipitates. " Applied physics letters80 (14): 2478-2480.) etc. method.On traditional preparation method basis, in order to overcome its all deficiency, people have proposed again the preparation method of various new amorphous and matrix material thereof.
Chinese Academy of Sciences's Shenyang metal patent " suspended smelting and spray-casting process of preparing lumpy amorphous alloy (publication number CN1361298A) " proposed by V-arrangement ruhmkorff coil the alloy pig suspended smelting being placed in V-arrangement quartz funnel, and obtain sheet non-crystalline material by the method for copper mold spray to cast.Invention is used the method suspending to prepare the problem that non-crystaline amorphous metal can avoid the impurity that usually can run in ordinary method to introduce; the method of casting by high-purity Ar gas blowout makes aluminium alloy contact as early as possible with mould; not only improve the speed of cooling of melt; and improve greatly the fillibility of melt; improved the precision of foundry goods, this research that is us provides a thinking.If but also be there are to some indeterminable problems in order to prepare the titanium-based amorphous matrix material of large size in the method: the V-arrangement quartz funnel that one is placed alloy at high temperature can with titanium generation strong reaction, in the time that suspended coil can not suspend aluminium alloy completely, still can cause because of reacting composition inaccurate; The suspending power of the suspended coil of its two suspended coil is limited, thereby has also just limited amorphous composite foundry goods to large-sized development; Can there is the problem of pore in the sample of its three spray to cast, affect the performance of foundry goods.
Lanzhou University of Science & Technology (Feng Liu. the preparation of copper-base lump non-crystalline alloy and performance test research thereof: [Lanzhou University of Science & Technology's master thesis].
