| Shrnutí: | Title screen The travel pattern of the nanostructured fibers of aluminium oxyhydroxide in the laminar flow of the argon carrier gas has been developed. On the basis of this pattern, the optimum range of the fiber size, providing the effective transportation of the modifying agent by the gas flows, is determined. Depending on the concentration of fibers, which are transported by the gas flow, the optimum technical parameters of the modifying agent of the aluminium oxyhydroxide for the austenitic steels are determined. The optimum concentration of the nanostructured fibers of aluminium oxyhydroxide in the argon carrier gas is determined. The modeling results and the efficiency of the developed method were verified by experimental researches for the depositing of the surface layers by the argon inert-gas arc welding (MIG welding). It was found that, during the modification of the surface layer, built-up by the nanostructured fibers of the aluminium oxyhydroxide at the amount of 0.2 mg/cm3, the maximum modification effect of this layer of the Fe–C–Cr–Ni–Ti system is expressed. The average size of dendrite shows a decrease of 4.5 times in width due to the formation of the additional centers in the melt being inoculants in the crystallizing metal. The share of the most favorable structure of the nonoriented dendrites in the bulk of the deposited layer increases from 43 to 62%. Режим доступа: по договору с организацией-держателем ресурса |
