| Popis: | The heterophase interaction of exogenous ZrO2 and Y2O3 nanoparticles with a surfactant (tin) in the Fe–Cr model system is studied with allowance for the use of oxide nanoparticles in the production of oxide dispersion strengthened steels. The study of the influence of the size factor demonstrates that the extreme values of the degree of tin removal are 15.4 rel. % for the Fe–Cr–Sn–ZrO2 system and 7.1 rel. % for the Fe–Cr–Sn–Y2O3 system. The sessile drop method is used to investigate the capillary properties of a metal with nanoparticles. The introduction of nanoparticles into the Fe–Cr–Sn melt is found to cause the inversion of coefficient ∂σ/∂T and the decompression of the melt. |
