Temperature is an important parameter under strong impact conditions to study the state of metal. It is very difficult to measure under high pressure because the short impact loading process and the high radiation temperature. In this work, the radiation pyrometer is used to study the radiation characteristics from metal interface. By improving the processing technology to the metal sample and assembly technology to the target, the stable history of radiation from the metal interface has been successfully obtained. It was confirmed that the temperature values is consistent with ideal model.
