Problems solved by technology
[0003] However, the ordinary uniaxial tensile testing machine cannot quench the specimen in time, and the method of dismantling the specimen and putting it into water for quenching is often adopted.
This method not only takes a long time, but also the temperature of the specimen changes during the disassembly process, which will affect the microstructure of the material
In addition, during the disassembly process, the specimen is in contact with air to form an oxide layer, which is not conducive to the observation of fracture morphology.

The invention relates to a fixture facilitating quenching treatment of a high-temperature single-pull sample, and belongs to the technical field of material detection. The fixture comprises a fixturebody, a test piece clamping block group, a clamping block fastening bolt, a guide block, a clamping block, a fixture loading part main body, a fixture loading part clamping block and a loading part fastening bolt. The fixture is simple in structure, and easy to machine, the required equipment cost for test is reduced, and the using method is simple and effective; a part of test pieces can be quenched rapidly after completion of high-temperature uniaxial tension test, so that the microstructure and fracture morphology of materials in the state are reserved to the maximum extent; and the microstructure change due to temperature drop before quenching, and the oxidation phenomenon due to long-time contact between the test pieces and air are avoided.
Description
technical field [0001] The invention relates to a fixture which is convenient for quenching treatment of a high-temperature single-drawing sample, and belongs to the technical field of material detection. Background technique [0002] Combining the tensile testing machine and the electric heating furnace, the mechanical properties of the material under high temperature conditions can be obtained through the high temperature tensile test. This experiment is of great significance to the study of the forming properties of the material. After the high-temperature tensile test, the specimen should be quenched in time, so as to effectively retain the microstructure and fracture morphology of the material at the end of the test, which is of great significance for analyzing the change law of high-temperature mechanical properties of the material from a microscopic perspective. [0003] However, ordinary uniaxial tensile testing machines cannot quench the test pieces in time, and the...
