Abstract

The invention provides a direct contact type stretching deformation measuring system in a high-temperature oxygen-free environment, and relates to the field of stretching deformation measurement in the high-temperature oxygen-free environment. The system comprises an environment casing, a radiation furnace, stretching clamps, a stretching sample, a first extensometer water cooling box, a second extensometer water cooling box, extensometer transmission rods, a first support adjusting device, a second support adjusting devices, elastic components and foil gauges, a signal line, a first fixed plate, a second fixed plate, an aviation plug, a signal amplification converter and a display. A direct contact type measuring method can be used to transmit deformation of the sample to the elastic components accurately, and the sensitivity is higher; and the test temperature can reach 2000 DEG C, the elastic components and foil gauges are kept below 50 DEG C always, and an extensometer can be calibrated in normal temperature and used in the high temperature environment.

Description

technical field [0001] The invention relates to the field of tensile deformation measurement of materials in a high-temperature anaerobic environment; in particular, a direct-contact tensile deformation measurement system and a measurement method in a high-temperature anaerobic environment. Background technique [0002] With the improvement of the performance of aerospace vehicles, traditional materials can no longer meet the design requirements. Through research and technological improvement, related industries have introduced a series of new materials that meet the design requirements, and put forward higher requirements for the performance indicators of new materials. Simulation The characterization of mechanical behavior in the service environment is an important indicator for evaluating the reliability of materials. Among them, the tensile performance test of materials in a high-temperature anaerobic environment is the most basic evaluation method. [0003] The high-te...
