Fabrication of submicrocrystalline structure in solid solutions by radiation-induced phase transition

The method of field ion microscopy was used to study the submicrocrystalline structure of the surface of PdCuAg solid solutions obtained after irradiation with Ar+ ions. It was shown that there are radiationinduced structural phase transitions in the subsurface volume of solid solutions irradiated by gas ions with an energy of 20 keV and a fluence of 10(18) ion/cm(2). The regimes were determined of radiation treatment of structural alloys Pd50Cu30Ag20 in which a microduplex-type structure with the phases' particle sizes being up to 100 nm with the necessary set of properties arises in the subsurface volume.
