High-temperature mobility of atoms of the components in the system molybdenum-tungsten

Summary The diffusion of both components in the system molybdenum-tungsten was investigated on alloys containing 0.1, 15, 20, 25, 35, 50, 65, 70, 80, 85, and 99.9 at.% tungsten. Experiments were carried out with the aid of Mo⁹⁹ and W¹⁸⁵ radioactive tracers in the temperature range 600–1000°C. The values of D₀ and E were calculated for all the alloys investigated.Translated from Poroshkovaya Metallurgiya, No. 11 (47), pp. 57–61, November, 1966.
