The invention relates to a high field high-temperature compression test device of solid materials, which comprises a stable high-voltage power source system used for providing various types of voltage, an electric field applying device used for making a test sample or test specimen (2) positioned in a uniform stable strong electric field, a heating and temperature control system used for ensuring the test sample or test specimen at a given temperature, and a loading and data acquiring system which loads the test sample or test specimen within the deformation velocity range of 0.02-100mm/min and can automatically detect the whole process of compression deformation. The invention can test the characteristic of high-temperature compression deformation of the materials in strong electric field environment, and related material shaping and processing technology is developed and seared on the basis, and real-time tracking, recording, data processing and display are carried out to the whole process of high-temperature compression plastic deformation. The complete set of device has the advantages of complete functions, high test precision, safety, reliability and convenient use.
