Abstract

The invention discloses a testing device for internal deformation and damage of materials at high temperature. The testing device comprises an X ray source (1) and an X ray detector (3) relative to the X ray source (1); the X ray source (1) and the X ray detector (3) are arranged at both side of the outer of a protective barrel (9), a loading stepping motor (4) is mounted on the upper end of the protective barrel (9), the lower end of the protective barrel (9) is mounted on a workbench (11), a lifting chuck (5) is mounted on an output shaft end of the loading stepping motor (4), a force sensor(10) is inserted in the workbench (11). According to the testing device provided by the invention, three-dimensional morphology of the material in a sample can be reconstructed by scanning the samplewith the X-ray source and the X-ray detector, the deformation information of the material in the sample can be calculated by comparing the changes of the three-dimensional morphology in the materialbefore and after loading.

Description

technical field [0001] The invention relates to the technical field related to material testing, in particular to a device for testing internal deformation and damage of materials in a high-temperature environment. Background technique [0002] The mechanical properties of materials in high temperature environment are of great significance to the engineering application of materials. The existing surface deformation testing technology is difficult to characterize the internal damage initiation and deformation evolution process of materials under high temperature environment. Contents of the invention [0003] The purpose of the present invention is to provide a material internal deformation and damage testing device under high temperature environment, which can effectively solve the problems existing in the background technology. [0004] In order to solve the problems existing in the background technology, it includes an X-ray source 1 and an X-ray detector 3 opposite ...
