Shallow talk about the casting of new-style material to make take shape

1. Agitate of grain of pottery and porcelain of ／ of liquid state metal casts figuration 　 to pass mechanical agitate to arise to eddy current introduces grain of pottery and porcelain thereby and make its distributing in liquid state metal even. Use this kind of method to make aluminium radical composite material, particle size of pottery and porcelain but small to 10 μ M, the bulk mark that gains wild phase can amount to 25 ％ . 2. Craft of ooze of dip of fuse-element of casting of fuse-element dip ooze includes pressure dip ooze and without the ooze that press dip. Former it is to use machine or inert gase to serve as pressure media to permeate metallic fuse-element macerate enter poriferous pottery and porcelain prefab piece in, but the composite material that class of preparation body integral is as high as 50 ％ , this method already was applied extensively. Latter is in nitrogen atmosphere falls not to need to bring to bear on any pressure alloy fuse-element soak powder of pottery and porcelain can goodly prefab piece in, but the composite material that preparation bulk mark is as high as 55 ％ . 3.

Crowded Die Casting makes a way this method has from mechanical agitate legal system compound oar expects first, next liquid state compound oar makings enters extrusion die (need warm-up) inside, starting hydraulic press, make liquid state oar expects it is certain to be in issue caky figuration than pressing. 4.

High-energy and supersonic law this method is to be after the metal is fused, use supersonic happening at the same time device (multi-purpose magnetism sends adjustable transducer) bring to bear on supersonic vibration, join grain of pottery and porcelain at the same time, after implementation mixes equably pouring figuration. Also can make grain of pottery and porcelain prefabricated component, after casting liquid metal, bring to bear on supersonic undertake fuse-element dip ooze. This method can be in cutty time (tens of seconds) those who realize grain is even distributing. 5. Stream change casting this law is intense to be in the fuse-element of area of solid fluid two-phase to bring to bear on churn the half solid state that forms low viscosity is serous, introduce grain of pottery and porcelain at the same time, use half solid state to be touched serously become characteristic and dispersive to add wild phase, fill below constant pressure model caky figuration. This craft is craft of a kind of two-phase, the alloy of limits of big crystallization of bureau be confined to. 6. Former a reaction casting a kind of this is the closest development brand-new method. It and the essential distinction of 5 kinds of afore-mentioned methods depend on: Enhancing grain of pottery and porcelain is not adscititious, pass chemical reaction to be in in preparation process however former generate. Its fundamental is: In certain liquid state alloy, use the high temperature of alloy fluid, make alloy fluid produces chemical reaction between the occasional alloying element of medium alloying element and compound, generate a kind or a few kinds of pottery and porcelain enhance grain, obtain through casting figuration next by former a metal that grain enhances base composite material. The preparation craft of composite material still is in metallic radical at present in considering to develop, be in afore-mentioned in all sorts of methods, what have industrialization perspective most is mechanical agitate casting. Because of its craft simple, cost is low, do not have limitation almost to fuse-element and the sort that enhance grain, have extensive adaptability. But should realize large-scale industry production to still need to solve the following problems truly: Grain is microcosmic the uniformity that distributing; Metallic matrix and strengthen the interfacial reaction between grain and control; Organization and function and stability.
