Abstract

The invention discloses a modular multi-atmosphere in-situ environmental stress instrument with wide temperature ranges. The modular multi-atmosphere in-situ environmental stress instrument comprises a mechanical loading module, a temperature varying module, an optical imaging and positioning module, an atmosphere module and a sensor system. The modular multi-atmosphere in-situ environmental stress instrument has the advantages that high-temperature and low-temperature modules can be switched over, so that mechanical tests can be carried out at extreme temperatures in the wide temperature ranges; a closed shell can be filled with different types of atmospheres, accordingly, single-axis in-situ mechanical tests can be carried out in multi-atmosphere environments, and displacement measurement, temperature measurement and mechanical measurement can be immediately carried out; the modular multi-atmosphere in-situ environmental stress instrument is mainly designed for synchronous radiation in-situ mechanical experiments and is modular, the wide temperature ranges, the multiple environments and multiple fields are coupled with one another, and mechanical, displacement and temperature measurement and feedback can be immediately carried out.

Problems solved by technology

However, at present, based on the research of synchrotron radiation X microdiffraction materials, experimental benches are needed to provide experimental conditions. At present, the existing experimental benches only have a single heating bench and cooling bench, and there is a lack of in-situ mechanics benches that can realize multi-environment and multi-field coupling.
