  • Abstract
    The results of experimental studies of the effect introduced into the molten pool of nanostructured powders of tungsten (W) and aluminum oxide (Al2O3) on the structure, morphology and dispersion of the deposited metal arc welding with consumable electrode gas-shielded. It is shown that the introduction of these powders decreases the size of the dendrite formed more equilibrium microstructure.
