    Effect of Heat Treatment on the Carbon Distribution in Zirconium and the Alloy Zr + 2.5%Nb

    x-Ray diffraction and Auger spectroscopy are used to establish that vacuum annealing of zirconium at 900–1200°C is accompanied by the formation of zirconium oxycarbide on the metal surface. The tagged-atom met...
