Properties of porous tungsten-copper and molybdenum-copper pseudoalloys
We obtained a complex of properties (hydraulic resistance, thermal conductivity, heat transfer coefficient) of the pseudoalloys W-Cu and Mo-Cu in the range of porosity 0.49–0.84 for different ratios of the high melting metal and copper. It was experimentally confirmed for the first time that the dependence of the heat transfer coefficient on porosity is extremal. It was shown that Koh's dependence for the calculation of the thermal conductivity of porous powdered metals can also be used for pseudoalloys with the same empirical coeifficient.
