INVESTIGATION OF THE FORMATION OF AN ALPHASOLID SOLUTION OF NITROGEN IN ZIRCONIUM AT HIGH TEMPERATURES,
Abstract
An investigation was made of high-temperature (1400-1700C) nitration of zirconium in a furnace with a molybdenum heater in an atmosphere of nitrogen which contains less than 0.005% of oxygen. By the methods of X-ray-photographic and metallographic analyses and the measurement of the microhardness, there has been established the conformity to law of the growth of the hardest layers-the -solid solution and nitride of zirconium ZrN. An equation has been found which connects the summary thickness of the films of ZrN and the alpha-solid solution with the temperature and time of the nitration, and the energy of the activation of the process of growth of the films has been calculated and it equals 56,290 cal/mole.
