Abstract

The invention relates to a combined load mode mechanical-electrical and thermal-magnetic coupling material performance in-situ test instrument and method, and belongs to the field of precise scientific instruments. The test instrument comprises three parts: namely a combined load-multi-physical field loading test platform, an in-situ monitoring platform and a vibration-isolating base, wherein the vibration-isolating base is mainly used for supporting the combined load-multi-physical field loading test platform and the in-situ monitoring platform, and provides a positioning service for installation of the platforms and effective vibration isolating treatment for various precise driving loading elements, detecting elements and in-situ monitoring elements; the in-situ monitoring platform realizes real-time dynamic and in-situ monitoring on micro deformation, injury mechanism, microstructure changes and property evolution of a material sample under the combined load condition by precisely adjusting the position and posture of various monitoring modules. The combined load mode mechanical-electrical and thermal-magnetic coupling material performance in-situ test instrument has the following advantages: the structure is miniaturized and lightened in weight, and the instrument body can be placed in an optionally equipped vacuum cavity, so that testing environments like low pressure, vacuum and inert gases can be provided for the material sample to be tested, and the practicability is high.

Description

technical field [0001] The invention relates to the field of precision scientific instruments, in particular to an in-situ test instrument and method for the performance of a force-electric-thermal-magnetic coupling material in a composite load mode. The in-situ test instrument and method for material microscopic properties under the combined load mode force-electricity-thermal-magnetic multi-physics field coupling loading conditions of the present invention can provide four mechanical loads of "tensile / compressive-low cycle fatigue-torsion-bending" One or more of them can also be used for typical functional materials to carry out microscopic performance tests under the multi-physical field coupling of "stress field-temperature field (high / low temperature)-electric field-magnetic field". Parallel load testing with coexistence of load modes. The in-situ micro-nano indentation test module embedded in the instrument can accurately measure the dynamic evolution of the indentation...
