A detection method for a detection device of an X-ray stress measuring instrument

Abstract

The invention discloses a detection method for a detection device of an X-ray stress measuring instrument. Through the co-inclination device of the goniometer, the ray source is controlled to rotate at an angle of θs, and the detector is rotated at an angle of θd to perform step-by-step scanning, so as to realize the co-inclination method for materials and material products Residual stress measurement; through the tilting device of the goniometer, control the ray source to rotate the θs angle and the detector to rotate the θd angle to perform step-by-step scanning, and realize the residual stress measurement of materials and material products by the roll method; fix the ray source rotation angle θs , the diffraction angle of the detector rotation angle θd on the crystal plane {H, K, L}, rotate the tilting device of the goniometer to make the goniometer rotate in equal parts, and the turntable rotation assembly collects data equidistantly within 360 degrees, Complete pole figure measurements. The invention provides the most reliable detection means for the research of new materials and the reliability of key components, and can realize residual stress analysis, residual austenite content and texture accurate measurement of multi-field material structures and irregular-shaped components .

Description

technical field [0001] The invention relates to a component stress measurement technology, in particular to a detection method for a detection device of an X-ray stress measurement instrument. Background technique [0002] At present, with the continuous development of new materials, new materials are widely used in various fields, and more and more new materials have entered people's lives. Domestic scientific research institutions are using more and more stress measurements on new materials, and their requirements are getting higher and higher. Most of their equipment comes from imports, but the use of imported equipment cannot fully meet the testing requirements, and the price is astonishing, the maintenance time is too long, and the maintenance cost Too high, to a certain extent, hinders the stress analysis of new materials, and cannot realize the residual stress analysis, residual austenite content and texture accurate measurement of multi-field material structure, irre...
