High-temperature fatigue force loading experiment instrument suitable for CT experiment

Abstract

The invention discloses a high-temperature fatigue force loading experiment instrument suitable for the CT experiment, an experiment sample is clamped and subjected to fatigue loading through a fatigue loading system, a supporting module is responsible for supporting experiment equipment, protective gas is introduced into a cylinder before the experiment is started, and after a period of time, thesample is heated and monitored in real time; and meanwhile, the rotating system is used for rotating the sample to enable the temperature of the experimental sample to be uniform, fatigue loading isconducted after the temperature is stable, and in the fatigue loading experiment process, the rotating system rotates the sample to conduct data information collection. A laser heating mode is adopted, and an optical material cylinder with high laser transmittance is used as a supporting structure, so that coupling of high-temperature heating, fatigue loading and CT experiments is achieved.

Description

Technical field [0001] The present invention relates to the technical field of mechanical experiments, and more particularly to high temperature fatterial loading experimental instruments suitable for CT experiments. Background technique [0002] In-situ high temperature fatigue mechanics loading experiment, is to study the microscopic evolution of the internal structure under the action of high temperature environment, which is important for understanding material failure failure mechanisms, optimizing material performance, and prevents the failure of materials. Fatigue is that the material is loaded under cyclic loading, and a partial permanent injury is generated at some point or some point, and the crack is formed after a certain cycle, or the crack is further expanded until completely break. [0003] In situ tomography (CT) is an important technical means for studying the three-dimensional microstructure of materials, but there is currently no high temperature fatigraphologi...

Problems solved by technology

However, the introduction of the cavity and thermocouples will affect the transmission of X-rays, that is, the information data collected

[0005] Further, in the CT observation fatigue loading experiment, the fatigue loading system will cause the information data of some angles to be blocked and cannot be collected

The current fatigue loading system is mostly in the form of supporting columns, which will block X-rays, so the information data of the blocked part is missing, which will affect the final experimental results
