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.
