Flux preparation method.
Background technology：
High temperature alloy is manufacture aero-engine hot-end component critical material, and the performance of high temperature alloy plays aero-engine
To very key effect.With the raising of engine intake temperature, to high-temperature alloy material performance, more stringent requirements are proposed,
Therefore it is badly in need of research and development temperature capability higher novel high-temperature alloy material.In the design process of high temperature alloy composition, one important
Thinking is exactly to add the refractory metal elements such as a large amount of Ta, Mo, W, Re and Ru to improve the temperature capability of alloy.
But the raising of refractory element can cause to form a large amount of harmful topological solid matter phases during being on active service
Low-alloyed high temperature creep property, seriously drops in (Topologically closedpackedphase, TCP phase).Currently, high
The design research and development of temperature alloy still rely on trial-and-error method to complete, by great wasting manpower and material resources.In recent years, China is to accelerate to close
The research and development speed of golden material realizes " double to halve " of R＆D costs and period that material genome project obtains the formal vertical of country
.
Material genome project include mainly high-throughput material calculate, high-throughput material experiment and database three parts,
Polynary section is spread as the key technology in high-throughput material experiment method, has been widely used in alloying component and tissue sample
It is high-throughput prepare, admittedly but this method is based on consolidate/spreading phase transition process, during cannot achieve aluminium alloy/solid phase change
Ingredient is prepared with the high-throughput of tissue, using the high Throughput Preparation based on liquid/solid phase transition process, can effectively enrich high pass
Technology of preparing is measured, R＆D costs and period are further decreased.
Invention content：
The purpose of the present invention is to provide a kind of high-throughput preparation method of high-temperature alloy material, this method is solidifying based on alloy
Gu liquid/solid phase transformation during makes metal derby or alloy block and high temperature by the control of the parameters such as directional solidification temperature and pulling rate
The generation element counterdiffusion of alloy melt is reacted, to realize control of the simple substance atom in the diffusion length of alloy melt, to
The control of regional area ingredient and tissue is obtained, it can be achieved that alloying component and being organized the formation of and the height that develops sample in process of setting
Prepared by flux, the efficiency of high-temperature alloy material research and development can be improved using this method, reduces R＆D costs and lead time.
The technical scheme is that：
A kind of high-throughput preparation method of high-temperature alloy material, is as follows：
(1) will be paraffin melting, melt paraffin injection is had in the metal die of step shape by wax injector, and keeps
It is cooled to room temperature to paraffin, forms wax-pattern；
(2) the blocky adhesive plaster that size is 5 × 5mm~15 × 15mm is sticked in and needs to place the pre- of metal derby or alloy block
Seated position, the position are any one face in five faces of wax-pattern top bar shape；
(3) corundum formwork is made by grout coating process in the wax-pattern combined, removes adhesive plaster after corundum formwork is made, and
The sintering of molding corundum formwork is carried out under the conditions of air atmosphere；
(4) it uses wire cutting that simple metal or alloy are cut into the size being adapted with step shape, and is removed by adhesive plaster
The metal derby or alloy block preset position window formed afterwards, is placed in the corundum formwork in step (3), and using schmigel to gold
The outer surface for belonging to block or alloy block is sealed, and prevents bleed-out in experimentation；
(5) formwork with metal derby or alloy block is placed in directional solidification furnace, is warming up to 1400~1600 DEG C, and will
Directional solidification is carried out after high temperature alloy melt cast to formwork.
In step (1), paraffin is melted at 50~80 DEG C for the high-throughput preparation method of the high-temperature alloy material, is led to
Wax injector is crossed by metal die of the melt paraffin injection with step shape, casting pressure is 0.5~2MPa, and at room temperature
Keep 1~10min.
The high-throughput preparation method of the high-temperature alloy material, it is rigid in 850~1000 DEG C of sinter moldings in step (3)
Beautiful formwork, sintering time are 1~3 hour.
The high-throughput preparation method of the high-temperature alloy material, in step (4), using wire cutting by simple metal W, Mo,
Hf, Re or W-Al, Ni-Ti alloys are cut into the size being adapted with step shape, and the shape of metal derby or alloy block is square
Or cuboid, it is mixed, the outer surface of metal derby or alloy block is carried out using mixture close with Ludox using schmigel
Envelope；In the mixture, based on mass percentage, Ludox is 5~15%, and schmigel is 85~95%.
The high-throughput preparation method of the high-temperature alloy material, in step (5), will carry W, Mo, Hf, Re metal derby or
The formwork of W-Al, Ni-Ti alloy block is placed in vacuum oriented consolidation furnace, is 0.01~10Pa, temperature 850~1000 in vacuum degree
DEG C sintering, to prevent metal derby or alloy block from aoxidizing, heat preservation 0.5~1h, be then warming up to 1400 with 10~30 DEG C/min
~1600 DEG C, 0.5~1h is kept the temperature, and by high temperature alloy melt cast to corundum formwork, under the conditions of pulling rate is 1~9mm/min
It is oriented solidification, passes through the diffusion between casting speed control metal derby or alloy block and liquid alloy.
Advantages of the present invention and advantageous effect are：
1, present invention process reasonable design reserves the sky of follow-up addition metal derby in traditional corundum formwork preparation process
Gap is formed using the reaction between powder in high-temperature sintering process to sky after the metal derby that size is adapted is placed in gap
Gap is closed, and has the advantages that operating procedure is simple, at low cost.
2, the preparation of the liquid state diffusion idol of different-alloy is realized in the diffusion the present invention is based on element in the liquid phase.
3, the present invention is easy to operate, and reasonable design, operability is strong, can significantly reduce and be tested in high-temperature material R＆D process
Amount and R＆D cycle and cost.
In short, the present invention, which solves multi-component diffusion section in material genome, can only realize the ingredient tissue ladder that solid/solid phase becomes
It spends the high-throughput of sample to prepare, and cannot achieve the high-throughput preparation problem of liquid/solid ingredient tissue gradient sample, be advantageously implemented
The target of " double to halve " in China's high-temperature alloy material R＆D costs and period, to accelerate the development of novel high-temperature alloy material to carry
For effective ways.
