Abstract
The present invention relates to an in-situ micro-nano impact indentation testing instrument, falling within the technical field of material micromechanical testing. The instrument comprises a nitrogen generation module, an environmental chamber, a high/low temperature loading module, an optical-infrared in-situ monitoring module, an electromagnetic-piezoelectric coupling impact module, etc. After the nitrogen is introduced into the environmental chamber and the test area is determined by microscopic imaging, the electromagnetic-piezoelectric coupling impact module can drive an indenter to indent a specimen. An acoustic emission sensor embedded in the high/low temperature loading module can monitor the surface crack propagation of the specimen. The optical-infrared in-situ monitoring module can perform real-time high-speed optical imaging and infrared imaging on the impact indentation process. The present invention can perform micro-nano impact indentation testing on the material at high or low temperatures.
