Abstract

The invention provides a unidirectional and bidirectional tensile test device for mesoscopic structure in-situ online observation. The test device includes a rack, and a transverse tensile mechanism and a longitudinal tensile mechanism mounted on the rack. A transverse guide rail and a longitudinal guide rail are mounted on the rack. The transverse tensile mechanism is mounted on the transverse guide rail, and the longitudinal tensile mechanism is mounted on the longitudinal guide rail. A single-shaft or double-shaft specimen is mounted on the test device through a clamping mechanism, single-shaft or double-shaft tensile test can be realized, and in the tensile process, in-situ observation of the mesoscopic structure can be realized through a metallographic observation platform. Compared with the prior art, the test device provided by the invention has the advantages of strong versatility, small volume, simple and compact structure, simple and flexible operation, and no noise pollution, etc.

Description

technical field [0001] The invention relates to a mechanical test device, in particular to a single- and double-way tensile test device for in-situ on-line observation of mesoscopic structures, which can be used for the in-situ testing of mesoscopic structures of metal and non-metallic materials in the process of unidirectional and bidirectional stretching Watch online. Background technique [0002] With the development of modern industrial technology, micro-electromechanical systems (MEMS), aerospace, medical, electronic communications, textile printing and dyeing, and pure hydrogen-fueled proton exchange membrane fuel cell (PEMFC) vehicles have greatly increased the demand for micro-components and products. Increase. However, the wide application of micro-components manufactured by traditional micro-processing technologies (such as ultra-precision machining, deep reactive ion etching, LIGA and quasi-LIGA technology, etc.) is greatly limited due to high manufacturing costs...
