| Abstract: | The measurement of thermal conductivity of W9Mo3Cr4V material at low temperatures 80K-300K has been carried out. Fluid nitrogen has been used to cool, and the stable state method has been used in the experiment. Using the metal material low temperature thermal conductivity testing device, made by Techical Institute of Physics and Chemistry of CAS, to accomplish the test. This tentative precision is high. The experiment has provided the essential data for computer simulation in the Deep Cryogenic Treatment of the high-speed steel cutting tools, which fills the domestic blank in low temperature parameter of the material. |
