(such as plant ash) prevents two pieces of husky model bondings.Two pieces of husky models are separated, take out the mould of casting, Sha Fan recloses to form cavity
Model is cast, molten metal is poured into after solidification to the model that goes to remove sand and obtains casting.
(2) method is forged.When the figure of buddha is bigger, figure of buddha making is carried out using the method that forges.Mainly carried out by metallic plate
Forging forms, then is effectively spliced.When producing the figure of buddha, it is necessary to first design drawing, and component is plotted to copper
On plate, the sequence that makes the figure of buddha must from top to bottom, usually the size of calibrated sizes and be made on a metal plate
Shape feature.In manufacturing process, for different moulding thus the type of tup be also classified into it is several:Include egg type, four
It is rectangular, delay oblique, wiredrawn edge shape and steeply inclined and hammer into shape.
Either Sha Fanfa still forges method and prepares the figure of buddha in Tibetan area, and the copper alloy of use is due to historical reasons referred to as profit
Agate.Riamb's alloy refers to alloyed copper, is originated from Tibetan language,《Hide Chinese voluminous dictionary》Explain that it is " referring to all kinds of loud copper products ".Riamb's alloy
Because being presented containing precious mineral, the object processed such as the metallic elements such as different proportion gold, silver, iron, lead and diamond, multicolored glass
Go out different colors or forms bright-colored color lump on surface.Generally speaking Riamb's conjunction is the general designation of various alloyed coppers, and various profits
Agate also has its corresponding time, value, color, packet slurry etc..
The Tibet of Riamb's alloy in ancient times is of great rarity, this is because：(1) Riamb's alloy materials are extremely rare.No
Only we seem the metals such as still very rare gold, silver today, also from multicolored glass surface of Western import etc..(2) sharp
It is bright-colored when agate alloy product new mint, and have peculiar light reflecting from metal inside.
Riamb's alloy is the distinctive copper alloy that Tibet region prepares the figure of buddha, has very excellent casting character.By
In figure of buddha size huge and modern people for the demand of figure of buddha quantity, Riamb's alloy of the casting figure of buddha has very big
Market demand.It is contemplated that the costliness and scarcity of copper, develop the novel non-copper with Riamb's alloy casting characteristics
Alloy carries out the replacement of Riamb's copper alloy, has extremely important meaning in today's society.But so far, due to material
The reason of design level, obtains effective solution not yet within considerable time.
Although China's religion ornament materials industry development is rapid, due to starting evening, starting point is low, on some sport technique segments
Also there is a big difference compared with world level.It develops and Riamb alloy replacing product of the industrialization with advanced feature is Tibet religion
The inevitable problem in field, domestic many research institutions and enterprise have carried out multi-faceted trial for a long time, but enable
People regrettably, not yet obtains the progress of any substance so far.It can pass through bottom by advanced design of material technology
The thermodynamics and kinetics means of layer property innovate Riamb's alloy replacing new material, and to developing and developing new material
Problem solves and industrialization has prodigious market value.In face of the domestic and international market competition being growing more intense, it is necessary to accelerate knot
Structure adjusts paces, this is the development trend of world today's related field.
Invention content
The purpose of the present invention is to overcome the deficiency in the prior art, and providing a kind of high elastic modulus, to have Riamb's alloy graining special
The kamash alloy of property.
To achieve the goals above, the present invention adopts the following technical scheme that：
A kind of high elastic modulus has the kamash alloy of Riamb's alloy graining characteristic.By weight percentage, the group of alloy becomes
B:0.5-0.6wt.%,Mo:0.3-0.5wt.%,In:2.0-3.0wt.%,Sb:2.0-2.5wt.%,Mg:3.0-3.5wt.%,Cr:
2.0-2.6wt.%,Co:3.0-5.0wt.%,Al:15.0-18.0wt.%, surplus are tin.A kind of above-mentioned high elastic modulus has profit
The kamash alloy of agate alloy graining characteristic, includes the following steps：As above the raw material matched is added to the induction under ar gas environment
In electric furnace, and use graphite crucible;10 minutes are kept the temperature at 400 degree when melting, it is uniform by Efco-Northrup furnace electromagnetic agitation;Stirring is equal
1 minute being kept the temperature at 400 degree after even and being cast come out of the stove;Alloy casting uses the punching block of diameter 20-30mm, and by the way of water cooling
Cooling.The ingot casting of gained is heated to 400-450 degree at room temperature and keeps the temperature 10 minutes;Then the melt is poured into and is ready for
Mold in carry out cast molding;It carries out eliminating casting stress vacuum annealing after cooling and demolding, temperature is 130 degree, the time
It is 0.5 hour.
Compared with prior art, the present invention has the advantages that：
（1）For technical term, the liquid alloy of traditional Riamb's alloy can generate Spinodal during solidification
Destructive effect generates two kinds of mutually insoluble liquid phases, thus the liquid phase of low melting point can compensate high-melting-point liquid in process of setting
The dendrite cavity generated when mutually solidifying, thus have the function of extremely beneficial.In comparison, it is solidified in general multicomponent alloy
In the process, with the generation of dendrite, interdendritic gap generates casting cavity and thin due to having little time to be filled by liquid phase
Pine.This alloy graining characteristic is very fatal defect for the large-scale statue of figure of buddha rank, and it is big not only to result in part
The cavity of amount generates, but also local material mechanical property deficiency and repairing become extremely difficult something.So Tibetan area
The excellent casting character for casting Riamb's alloy of the figure of buddha is undivided with the excellent coagulating property of its material.Modern age is to profit
Agate figure of buddha alloy research shows that, a certain amount of lead and mercury are usually added into Riamb's alloy.It is closed since lead and mercury are not formed with copper
Gold, in the solidification of Riamb's alloy, with the continuous solidification of Cu rich alloy, the liquid phase of rich lead and mercury is also constantly from initial
It is separated in alloy melt.These rich lead and mercury melt are thus adjoint in process of setting since discord copper-rich melt mixes
It the generation of dendrite and is gradually squeezed in the gap of dendrite, and finally solidified in these narrow gaps, play benefit
Fill the effect in solidification cavity.The copper alloy for being thus added to appropriate lead and mercury is extremely suitable for casting the large-scale statue such as figure of buddha,
Because the defects of solidification that this material generates is empty is few.Although traditional Riamb's alloy is particularly suitable for using casting or forging
The method beaten prepares bronze statue, it is contemplated that the price of copper costliness, the every copper demand of honor bronze statue and total to bronze statue at present
The potential demand of amount develops a kind of novel no copper alloy having coagulating property possessed by Tibet Riamb alloy, for reducing
Cost and exploitation religion trim-alloy new material have extremely important realistic meaning.
