Abstract

The invention discloses a tensile mechanical property testing device applicable to high-temperature vacuum. The tensile mechanical property testing device comprises an environment control unit and a deformation measurement extensometer. The deformation measurement extensometer comprises a first extension pole and a second extension pole and is arranged on the side face of the environment control unit, the first extension pole is used for butting against the top end of a test sample, the second extension pole is used for butting against the bottom end of the test sample, and the tensile of the test sample corresponds to a distance difference value of the first extension pole and the second extension pole before and after testing. The tensile mechanical property testing device applicable to the high-temperature vacuum has no effect on testing results when the extension amount of the extension poles changes in a high-temperature environment so as to reduce errors of the testing results.

Description

technical field [0001] The invention relates to the technical field of material performance testing, in particular to a tensile mechanical performance testing device suitable for high-temperature vacuum. Background technique [0002] The mechanical properties of materials refer to the mechanical characteristics of materials when they are subjected to various external loads (tension, compression, bending, torsion, impact, alternating stress, etc.) under different environments (temperature, medium, humidity). Such as figure 1 As shown, in the existing tensile mechanical performance tests, most of the upper chuck 1 is connected with the upper link 3 through the upper pin 2, the lower chuck 4 is connected with the lower link 6 through the lower pin 5, and the deformation of the lower link is set. The extensometer 8 measures the tensile mechanical properties of the sample through the elongation of the extension rod 9 of the deformation extensometer during the tensile test of the...
