Description
Technical field:
The invention belongs to sample grinding and polishing fields, and in particular to a kind of drawing by high temperature sample grinding and polishing apparatus and its application method.
Background technique:
During carrying out the grinding and polishing of thin plate, band, light sheet tensile sample, need tensile sample to be surface-treated clean
(removing oxide layer and decarburized layer), the surface roughness of tensile sample parallel-segment is small as far as possible, grinding and polishing along draw direction sample
Thin and thick will as far as possible uniformly, if the grinding and polishing uneven distribution along draw direction sample will lead in drawing process sample in thin location elder generation
It is broken, leads to the problem of experimental result inaccuracy.Some tensile samples are non-standard samples, such as: high-temperature laser copolymerization is burnt
Microscope tensile test at high temperature, sample size is smaller, and the grinding and polishing difficulty of this kind of sample is bigger.
High-temperature laser Laser Scanning Confocal Microscope is Japanese Lasertec company by common focus point migration, infrared heating, stretching
Etc. technologies combine, being can be with the confocal laser scanning microscope, CLSM of home position observation material at high temperature microstructure Evolution.
The product can carry out the home position observation of sample topography under the condition of high temperature.It is that intuitive research material melts, solidifies, is high
The important tool of the processes such as warm stretching, martensitic traoformation.The characteristics of high-temperature laser Laser Scanning Confocal Microscope drawing by high temperature compression module
It is:
(1) heating speed is fast, can be heated to 1200 DEG C by room temperature in 30 seconds.
(2) it most can achieve the rapid cooling of -100 DEG C/sec when chilling mechanism forced using He gas fastly.
(3) effective heating area domain is larger, can achieveRange, convenient for carrying out height
Suitable viewing area is found when warm stretching experiment.
(4) drawing by high temperature and high temperature compressed combination can be tested, tension and compression combine, and simulated experiment sample engineering is practical
Service Environment keeps experimental data more targeted.
The preparation requirement of high-temperature laser Laser Scanning Confocal Microscope drawing by high temperature compression module sample:
(1) sample surfaces levelness wants high, and it is uniform that the parallel-segment of tensile sample has to polishing；If sample surfaces are horizontal
Spending poor or polishing unevenly will lead to sample surfaces there are certain altitude difference or wavy grinding and polishing line, carry out drawing by high temperature examination
Sample is broken along thinner region when testing, and cannot really reflect material at high temperature tension failure situation, influences the accuracy of experiment and true
Reality.
(2) sample surfaces roughness is low as far as possible, and sample surfaces try not have scratch.
The reason of requiring in this way is if sample surfaces roughness is excessively high, and scratch is more, sample during high-temperature heating
The variation that product surface is generated because temperature changes can be because scratch and defect and the difference in height of sample surfaces have exceeded microscope mirror
Head field depth, high-temperature metallography observation when can not shape library, cannot lead to not observe at clearly high temperature observation picture
Real-time situation under material at high temperature when test.
The preparation of high-temperature laser Laser Scanning Confocal Microscope drawing by high temperature compression module sample there are the problem of or difficult main packet
Include the following aspects:
(1) abrasive dust generated in sample bruting process is easy adhesion sample surfaces, pollutes.
The preparation of sample: tensile sample generally requires the mill of not jack per line sand paper before carrying out structure property morphology observation
System, is divided into corase grinding and fine grinding two procedures.Corase grinding: the purpose of corase grinding is that the rusty scale and impurity in order to remove sample surfaces obtain one
A even curface.Fine grinding: though specimen surface is more smooth after roughly grinding, but still there is also have deeper polishing scratch.The purpose of fine grinding
Exactly in order to eliminate these polishing scratch, to obtain smooth and smooth flour milling, it is ready for the polishing of next step.In the mistake of fine grinding
Cheng Zhong by adding water mill system that sample surfaces state can be made more preferable on sand paper, but it is noted that prevents the abrasive dust in grinding process
It sticks in sample surfaces and causes secondary pollution.It is finally polished again by polissoir, carries out the morphology observation of next step.
(2) it is big that difficulty is polished in sample polishing process.
Since drawing by high temperature sample is than relatively thin, specimen size is smaller, during polishing, uses hand under the high revolving speed of polishing machine
It is difficult to hold, polishing difficulty is big, and sample is easy to hurt sb.'s feelings if flown out during the polishing process.
(3) the surface grinding and polishing ripple glaze that polishing process generates is difficult to remove.
Tensile sample will keep being flattened on polishing panel surface during polishing, under the high revolving speed of polishing machine, can only use hand
Sample is pushed down, but uneven because of the power that finger applies sample, leading to tensile sample, stress area is uneven along its length,
Sample polishing degree is different and surface is easy to produce ripple glaze, these defects are difficult to eliminate and cause very to subsequent high temperature observation
Big influence.Tensile sample surface quality, roughness, scratch are difficult to control, and experiment success rate is lower.
(4) unbalance stress of the sample on draw direction.
It during polishing, press...withes one's finger and is pressed in sample surfaces, because the power that finger applies sample is uneven, cause
There is mill along draw direction, throws the different situation of degree along draw direction unbalance stress, sample in sample, causes sample along stretching side
To in uneven thickness, the ratio that some places can be ground is relatively thin, causes very big influence to the result of subsequent tensile test at high temperature.
Can not reaction material true tensile strength and the region of fracture, experimental data can not repeat.
(5) observation panel has fluctuation in the experimentation under high temperature, can not clearly observe in real time.
Main cause is: high-temperature laser Laser Scanning Confocal Microscope uses observation window gas flow purging mode, the purpose for the arrangement is that
So that the impurity sublimate that will not be discharged during heating because of sample on observation window is attached to watch window, influence to see
It examines；Clearly observing effect can be kept using observation window gas flow purging mode for a long time.But meanwhile if sample surfaces roughness
Greatly, the defects of there are wave grinding and polishing lines, scratch, during heating with the purging of high-speed flow, will lead to high-temperature metallography figure
As shake, the variation of visual field shading value is excessively obvious, steady and audible can not be imaged, can not be to the variation progress of sample surfaces under high temperature
Clear observation in real time.
