Description
Technical field
The present invention relates to a kind of anvil for producing high pressure, specifically, be in the Static pressure device of octahedron pressure chamber
The mutli-anvil apparatus used.
Background technology
Static pressure technology is to utilize external mechanical load mode, extrudes by handled object slowly applies load,
So that its internal a kind of technology producing the highest pressure and the long period being kept.Static pressure experimental technique is divided into large cavity
(sample size is more than 1mm 3 ) Static pressure technology and diamond anvil cell (DAC) technology.Large cavity Static pressure device presses pressure
The mode produced is divided into one-level large cavity Static pressure device and two grades of large cavity Static pressure devices.One-level large cavity Static pressure device
Mainly include top, two sides and pressure chamber, one-level multiaspect top device.Two grades of large cavity Static pressure devices are also known as octahedra press, by eight
The compress cell of mutli-anvil apparatus and octahedra transmission medium composition produces high pressure, and mutli-anvil apparatus typically uses tungsten carbide anvil.
In the device of one-level hexahedron pressure chamber, owing to top hammer is mounted in big cushion block and the use of small cushion block top of hexahedral press piston
, when the square high pressure chest formed by hydraulic oil cylinder driving hexad top hammer Guan Bi, can reach the pressure of more than 6GPa and take the photograph
The temperature that family name is more than 1500 DEG C；For two grades of octahedra pressure chamber devices, eight mutli-anvil apparatus within one-level square high pressure chest
The producible highest pressure in octahedra pressure intracavity portion that anvil face Guan Bi is formed is about 25GPa.
Mutli-anvil apparatus generally uses hard alloy to make, and is under high-temperature and high-stress state during high temperature and pressure experiment
Work, and subject compressive stress, tension, shear stress etc. acts on, it is therefore desirable to have the highest intensity.Produce height being used for
In the high temperature and pressure experiment of pressure and production process, the stress distribution that anvil is born is uneven, and easily concentrates on anvil body point
Position, end, thus cause anvil corner position and seamed edge crackle occurs or collapses the situation on limit, this anvil is produced permanent
Destruction makes anvil lose efficacy, therefore, manufacture and design one both may be used for produce high pressure, the anvil that can repeatedly use again,
The utilization rate of anvil will be effectively improved, reduce experiment or production cost.
Summary of the invention
It is an object of the invention to easily collapse limit, service life short deficiency for existing anvil, it is provided that one is used for producing height
The anvil of pressure, by the Quantitative design of chamfering, eliminates or extenuates the concentration of stress so that answering in anvil during High Temperature High Pressure
Power is dispersed, and substantially increases the pressurized effect of anvil, comprcssive strength and service life.
The purpose of the present invention is realized by techniques below measure:
Being square for producing the anvil anvil body of high pressure, anvil face is to cut a dihedral at a drift angle of square body stock body to become
Equilateral triangle face, the length of side of anvil face is the 5%～60% of anvil body cubic block side length.For different experiment demands, can be
Equilateral triangle anvil face is set at multiple drift angles in one anvil.During assembling, the ladder that cross section is isosceles trapezoid is set at anvil face edge
Shape block, as sealing strip 2, arranges cushion block 3 on non-anvil face, in pressure process sealing strip 2 and cushion block 3 eight anvil are separated with
Protection anvil and octahedra pressure within transmission medium Synthetic block 4, by the two-stage supercharging of eight anvil one squares of composition
Unit 5, the anvil face of eight anvil bodies surrounds an octahedral synthesis chamber, and the sample assembly that will test is at octahedra transmission medium
It is placed in again after in Synthetic block 4 in synthesis chamber and tests.The rib of anvil is processed as chamfered edge or chamfering structure, and anvil body drift angle is processed as
Chamfering structure, this chamfered edge and chamfering structure can make the stress in anvil disperse after high temperature and pressure experiment and homogenization, keep away
Exempt from stress and excessively concentrate the situation and the anvil that causes is burst apart.The rib of anvil of the present invention is tied with chamfering with the chamfered edge of drift angle
Structure, including bevelling and rounding two kinds, can use and outward appearance need according to the different of chamfering structure concrete to anvil aborning
Ask and process respectively.On pretreatment the rib of anvil body is processed as the rounding structure that radius is 0.01～5mm, the chamfering of anvil body drift angle
It is processed as the rounding structure that radius is 0.01 mm～5.0 mm, can further improve anvil service life in an experiment.
Anvil of the present invention can use tungsten to bore serial carbide alloy, mould steel class alloy, diamond, cubic boron nitride polycrystalline burning
One or more in knot body and composite thereof are compound to be made, and common are Talide anvil, its crystallite dimension
Generally submicron, to several micron levels, is 1%～20% containing cobalt amount, also Talide pressure compound with polycrystalline diamond
Anvil.
The length of side of anvil anvil face of the present invention is the 5%～60% of anvil body cubic block side length, and the length of side of anvil face accounts for anvil
The ratio of body cubic block side length is the highest, and the amount of the sample that can put into assembling is the most.
The part effect being used for high temperature and pressure experiment after anvil of the present invention is processed into different chamfered edge and chamfering kind is as follows
Shown in table:
Owing to the rib of anvil is set to chamfered edge or rounding structure by the present invention, anvil body drift angle is set to chamfering structure, it is to avoid or bright
The aobvious anvil stress in use that slow down is concentrated, and reduces the anvil probability that bursts apart during High Temperature High Pressure produces,
After particularly rib and drift angle being carried out rounding process, anvil can under producing 15GPa, the high-temperature and high-pressure conditions of more than 2000 DEG C
To reuse more than 5 times, produce less than 10GPa condition of high voltage under reusable more than 10 times, improve anvil
Utilization rate and service life, reduce the cost of use.
