摘要：

Processes of mechanical alloying of oxide-dispersion-strengthened reactor pressure-vessel steels by cold high-pressure torsion of a powder mixture of low-stable Fe2O3 (Fe3O4) iron oxides and the bcc matrix alloyed with Y and Ti have been investigated using Mossbauer spectroscopy, X-ray diffraction analysis, and electron microscopy. Some features of decomposition of iron oxides and phase transformations in the matrices synthesized by mechanical alloying with formation of solid solutions supersaturated with oxygen and various compounds of oxygen with iron and alloying elements, in particular, special nanooxides of yttrium and titanium have been established.
