Problems solved by technology

Thirdly, most of the existing high-temperature deformation measurement technologies are limited to plane measurement, which cannot reflect the real three-dimensional deformation of materials during high-temperature deformation; most of the existing temperature field measurement technologies are contact measurements, and can only measure single points Temperature, the measurement range of non-contact measurement is limited, and it is impossible to measure the high temperature distribution in the whole field
