Dual cooperative induction temperature control device and control method for micro-nano impact indentation tester

A dual cooperative induction temperature control device for a micro-nano impact indentation tester, comprises:

• a first cavity arranged in a pressing rod;
• a second cavity arranged in a stage, wherein a phase change heat storage material is placed in the first cavity and the second cavity, and a phase change temperature of the phase change heat storage material is a target temperature for testing a specimen fixed on the stage;
• a first electromagnetic induction heater configured to perform non-contact heating on the pressing rod;
• a second electromagnetic induction heater configured to perform non-contact heating on the stage;
• temperature detection mechanisms configured to detect a temperature of the specimen and an indenter, wherein the indenter is fixed at one end of the pressing rod facing the specimen;
• a data collector configured to collect and record data of the temperature detection mechanisms, the first electromagnetic induction heater and the second electromagnetic induction heater;
• and
• a data processor configured to analyze the data collected by the data collector and judge whether the phase change heat storage material stores heat through phase change in the heat absorption process and whether the phase change heat storage material is in the phase change stage in the heat release process.
