Abstract

The invention discloses an in-situ test device for three-dimensional defect reconstruction. The in-situ test device comprises a hollow framework structure and a transmission mechanism, wherein baffles are symmetrically arranged on the left and right sides of the framework structure respectively, a left crossbeam and a right crossbeam are connected in a sliding manner between the baffles through a guide rail, a rotating lead screw connected with the left crossbeam and the right crossbeam is further arranged between the baffles, and a lifting electric motor connected with the rotating lead screw is arranged on one side of the framework structure; and tail shafts with synchronizing wheels are respectively arranged on the left crossbeam and the right crossbeam, a load sensor connected with the tail shafts is arranged on the left crossbeam or the right crossbeam, clamps for loading test pieces are connected to the tail shafts, a stepping motor is arranged at the lower part of the framework structure, and a grating ruler is arranged at the upper part of the framework structure. By virtue of combined use of the in-situ test device and an X-ray detection instrument, the automatic rotation of the test pieces can be realized in situ under the loading condition, so that the X-ray transmission imaging is realized, and phenomena of formation, expanding paths and expanding rate of microcracks of materials can be observed online.

Description

technical field [0001] The invention relates to an in-situ tension-compression and fatigue test device for micromaterials, more specifically, relates to a three-dimensional defect reconstruction in-situ test device for research on internal structure changes and performance changes of micromaterials. Background technique [0002] In materials science, the macroscopic properties of materials are closely related to their microstructure. When the distribution of material microstructure is not uniform, traditional two-dimensional material characterization techniques such as metallographic microscope or scanning electron microscope are difficult to provide complete internal information of the material. The relationship between material microstructure and macroscopic properties cannot be accurately established, and quantitative information such as the quantity, volume fraction and distribution of material microstructure in three-dimensional space cannot be obtained. [0003] At pr...
