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 measuring tensile deformation of materials in a high-temperature oxygen-free environment; in particular, it relates to a direct contact type tensile deformation measurement system and a measurement method in a high-temperature oxygen-free environment. Background technique [0002] With the improvement of the performance of aerospace vehicles, traditional materials can no longer meet the design requirements. The related industries have introduced a series of new materials that meet the design requirements through research and technological improvement, and put forward higher requirements for the performance indicators of the new materials. The characterization of mechanical behavior under the use environment is an important index to evaluate the reliability of materials. Among them, the tensile performance test of high temperature oxygen-free environment is the most basic evaluation method. [0003] The high-temperature m...
