Description
Technical field
The utility model belongs to testing of materials device field.
Background technology
The metal material mesoscopic mechanics is the research means of the new material deformation behavior of research between the crystal structure yardstick of the material behavior of macro-scale and microcosmic.The object of metal material mesoscopic mechanics research is material mesoscopic agglomerate (group that becomes between the crystal grain group of metal material between macro-scale and the micro-scale), under load situation in real time, and the deformation rule and the fracture behaviour of be situated between sight substructure and dynamic structure.Mesoscopic mechanics test device for metallic material is a kind of new means of testing of metal material evaluating characteristics.Metal material characteristic evaluating in the past only is divided into two big classes, and the one, the Mechanics Performance Testing analysis of macroscopic view, comprising YIELD STRENGTH, fracture strength, the mechanics evaluation index of macroscopic view such as elongation and hardness.Another kind of be by with analysis means, the micromechanism of analysis of metallic materials, microscopic appearance, composition and metallographics such as high-resolution microscope.It should be noted that and between the two, exist a bigger space, from the macroscopic view to the micro-scale, cross over and be approximately four orders of magnitude, this has just caused the correlativity between two kinds of evaluation results relatively poor, and the influence factor that the contact between two kinds of evaluation results is subjected to is complicated, be that the shared proportion of each microcosmic result is very small, other as a result factor of influence will seem strong, and having covered the influence of original result to the macromechanics behavior, this just feasible fabric analysis gained result with microcosmic comes the macro-mechanical property of building material to have certain difficulty.This is the major issue that metal material research faces.This has done a few thing on the one hand at mesoscopic mechanics in present Russian state, and Muscovite material mesoscopic mechanics testing apparatus is not installed displacement extensometer, the dependent variable that does not have synchronous recording sample stand under load to cause on sample.Can not obtain the ess-strain amount of material.Can not obtain the ess-strain information of material, will influence gained result's scientific value, catch less than the closely-related information of material real behavior.
Summary of the invention
The purpose of this utility model provides a kind of mesoscopic structure, ess-strain behavior that can be used for observing material deformation, plastic flow and cracking between macroscopic view and micro-scale.And real-time analysis and finder are carried out in the equivalent amount of the whole audience, deformation spinor field and the strain of the sample in material deformation process field.
The utility model is made up of following part: sample coaxial to draw, to pressing loading bench 1, optical imaging device 2, ccd image receiving trap 3, power value sensor 4, small-sized folder formula displacement meter 5, device control desk 6, computer 7.Sample is coaxial to drawing, to pressing loading bench, its type of belt drive is same through-drive, small-sized folder formula displacement meter 5 is stuck in the sample stage casing, optical imaging device 2 is placed on and adopts built-in light source above the sample, compound lens, ccd image receiving trap 3 connects optical imaging device, be placed on above it, power value sensor 4, be positioned at a side of sample, when sample loads, induce faint output electric signal, simulating signal is amplified through amplifying circuit by Setup Controller 6, be converted to digital signal, input computer 7, the distortion of sample part of the force is by the faint output electric signal of small-sized folder formula displacement meter 5 inductions, simulating signal is amplified through amplifying circuit by device control desk 6, be converted to digital signal input computer 7, computer carries out in real time, receive simultaneously and handle to be situated between and see image and load strain signal, edit storage and handle the equivalent amount of strain field, deformation spinor field and ess-strain signal are data file.
Advantage of the present invention
The material mesoscopic mechanics scope of development is the instrument that is used for research material deformational behavior under meso-scale.The foundation of material mesoscopic mechanics tester provides information meso-scale, the fracture rule to investigation of materials.Material mesoscopic mechanics is the importance of can not ignore of investigation of materials, is the new cognitive domain and the research direction of metal physics.Carry out the research of mesoscopic mechanics, set up the mesoscopic mechanics research means, further the both macro and micro structure is combined, for the research of metal physics provides a new research means to be very important.
The development and application of material mesoscopic mechanics proving installation is to the great significance of material science, on academic significance and application prospect wide, remote is arranged.

Embodiment
Consult Fig. 1 with the test button surface finish to the metallographic requirement, and etch goes out the metallographic pattern, then sample is installed on two-way loading to draw, to pressing on the testing table, sample is loaded, this moment, connected power value sensor 4 induced load signal, and be stuck in the middle part of sample simultaneously with small-sized folder formula displacement meter 5, synchronous recording is because the strain signal that the sample stand under load causes, with two kinds of signal input apparatus control desks 6, by A/D signal translating system input computer 7, after editing and processing, draw and preserve the strain curve of its power value.When sample loads, optical microscope that assembles in the polished surface top of sample and image capturing system 3 are through device control desk 6, through conversion of signals input computer, power value-strain curve and dynamic profile with synchronization after editing and processing show on same plane, and storage, can call at any time, the dynamic profile image obtains strain equivalent amount field data and deformation spinor field data in the field of view through the information processing of computer.
