Abstract
The present invention relates to an amorphous material, particularly to a multi-component bulk amorphous alloy material with a large supercooling liquid region and high thermal stability. The multi-component bulk amorphous alloy material comprises the following six components: Zr, Cu, Ni, Al, Hf and Ti, and the multi-component bulk amorphous alloy material has the components by the following atomic percentage: 56 to 60 of Zr, 18 to 22 of Cu, 8 to 10 of Ni, 6 to 10 of Al, 2 to 3 of Hf, and 2 to 4 of Ti. The problems of the smallness of the supercooling liquid region and the lowness of thermal stability of existing bulk amorphous alloys without beryllium are greatly solved. The bulk amorphous alloy material of the present invention has the characteristics of high hardness, high strength, high elasticity, high corrosion resistance and abrasion resistance, and is suitable to be used in the fields of aviation, spaceflight, electronic packaging, micro electromechanical systems, high-grade sport equipment, etc.
Description
Technical field: the present invention relates to a kind of amorphous material.
Background technology: bulk amorphous alloys (Bulk amorphous alloys also claims block metal glass) has developed very rapid since the early 1990s occurs.Now expand to zirconium base and other alloy systems from early stage palladium (Pd) base and lanthanum (La) base, wherein especially with zirconium-base amorphous because of glass forming ability by force, better heat stability and starting material are cheap relatively especially comes into one's own.The zirconium base alloy composition that has developed at present is up to tens of kinds, and the overwhelming majority is covered by developed country's patents such as Japan and the United States.Its supercooling liquid phase region is all little except the alloying constituent that contains beryllium (Be) series simultaneously, and thermostability is relatively poor.And contain the beryllium composition because of the huge poison of beryllium element, and in production and use, all can produce certain harm, limited the range of application and the degree of block non-crystalline alloy material.Therefore, the development large block amorphous composition that does not contain beryllium element novel, that have big supercooling liquid phase region is the target that the various countries scientist pursues unexpectedly mutually.
Summary of the invention: the invention provides the multicomponent block non-crystalline alloy material of a kind of big supercooling liquid phase region and high thermal stability, it has solved better, and existing not contain the existing supercooling liquid phase region of beryllium bulk amorphous alloys less, the problem that thermostability is relatively poor.Multicomponent block non-crystalline alloy material of the present invention has following six constituent element: Zr, Cu, Ni, Al, Hf, Ti, and the atomic percent of each constituent element is: Zr56～60, Cu18～22, Ni8～10, Al6～10, Hf2～3, Ti2～4.Supercooling liquid phase region is one of bulk amorphous material most important characteristic parameter, and it is defined as: Δ Tx=Tx-Tg, and wherein Tg is a glass transformation temperature, Tx is a crystallization temperature.Supercooling liquid phase region is measuring of alloy thermostability, can be interpreted as generically that alloy remains the ability of noncrystalline state, the supercooling liquid phase region that is alloy is big more, and the thermostability of non-crystaline amorphous metal is high more, resists crystallization under certain condition, keeps the ability of noncrystalline state strong more.Furthermore, big supercooling liquid phase region also helps the follow-up moulding process of alloy, makes it and can realize forming process in wideer process parameters range.The supercooling liquid phase region of block non-crystalline alloy material of the present invention is big, be 144K, being far longer than this index of other composition that does not contain beryllium, be 106K only as the Δ Tx of ZrCnNiAl system, be present except that such alloy that contains beryllium the bulk amorphous alloys of supercooling liquid phase region maximum.It has Heat stability is good, does not contain the advantage of poisonous element.Block non-crystalline alloy material of the present invention has the characteristics of high rigidity, high strength, snappiness and high anti-corrosion and wear resistance on performance, it is suitable for each field such as Aeronautics and Astronautics, Electronic Packaging, MEMS (micro electro mechanical system), high-grade sports equipment and uses.
