Abstract

The invention discloses an in-situ ultra-high temperature tensile experimental device based on a computed tomography system. The device comprises a CT test system for in-situ observation of an ultra-high temperature tensile specimen, a loading system for applying a load, a loading control system for controlling the loading system, a heating system for heating the sample, a temperature measurementsystem for measuring the ambient temperature of the sample, a protection gas device for simulating the gas environment under the service conditions of the sample, and a temperature control system forcontrolling the heating system and receiving temperature information fed back by the temperature measurement system. The heating system is respectively connected to the temperature measurement systemand the loading system. The loading system is connected to the CT test system. Based on a CT platform, the conductive material is subjected to tensile loading in an ultra-high temperature environmentand the change of the internal appearance of the conductive material is detected in real time.

Description

technical field [0001] The invention relates to the technical field of high-precision industrial computerized tomography (CT) systems, in particular to an in-situ ultra-high temperature tensile test device based on the computerized tomography system. Background technique [0002] The influence of the temperature field on the properties of the material is extremely significant. The material exhibits different thermo-mechanical properties at different temperatures. Especially under high temperature and ultra-high temperature conditions, the thermo-mechanical properties of the material are greatly different from those in the normal temperature environment. , the study of the ultra-high temperature mechanical properties of materials has important guiding significance for the optimal design of material structures and the improvement of reliability during service, and is of great significance for evaluating the deformation and damage mechanisms of materials under high temperature c...
