Description
Technical field
The utility model belongs to sample Mechanics Performance Testing field, is specifically related to a kind of micro-test sample clamping device that carries out metallographic grinding for clamping micro-test sample.
Background technology
In thermoelectricity, nuclear power, petrochemical industry and metallurgy industry, there are a large amount of inservice pressure vessels and pipeline, the material of these pressure vessels and pipeline can be subject to damage in various degree after the lower military service of certain environment (high temperature, corrosion etc.), for the security of objective assessment device the residual life of predict device, must accurately obtain the mechanical property of its material.Is the most also that way is that the sample that equipment is damaged extracts the most accurately, then method is routinely carried out the test evaluation of the various performances of material, but this way has obvious damage and fracture to original structure, has usually limited the evaluation of in-service equipment.
Therefore, gradually adopted at present micro-test sample technology, from equipment take off be not enough to equipment form damage compared with small sample, then it is studied, so just can address the above problem real assessment device security.
Be illustrated in figure 1 the test philosophy figure of micro-test sample method (hydraulic pressure bulging method), micro-test sample 1 is gripped by upper fixture 2 and lower clamp 3, load application P on micro-test sample 1, test its displacement by displacement conduction device 4 and displacement transducer, since its small specimen size, simpler experimental facilities, more real load mode, factor of influence still less, more reliable experimental data, has application prospect more widely.In engineering reality, during from in-service equipment sampling, may there is the situation that sample thickness differs, and to micro-test sample technology (little jumper bar, hydraulic pressure bulging) micro-test sample test has high sensitiveness to sample thickness, therefore considers that sample thickness is necessary on the impact of result of the test.
