Structural-phase mechanisms of controlling the structural and functional alloys complex surface properties by combined thermal, ionic and deformation effects

The perspective of using combined thermal, ionic and deformation effects as a tool for purposeful modification of the structural and phase states of the near-surface region of a wide class of structural and functional metal materials to increase the durability, quality and reliability of parts, products and structures of transport engineering and medicine has been proven. Steels 40X13, 08X18N10, 9Г2ФА, aluminum alloys AMg6, D16, cobalt alloy Co-Cr-Mo-W, brass LS59-1, titanium alloy VT6, multi-component alloys Fe81B7Si1P10Cu1, CrMnFeNi2CoCu, etc. were studied.

Influence of ion irradiation on structure, absorption capacity and corrosion properties of nanosized metal compositions

It is shown that the method of bombardment of a nanothick vacuum-condensed metallic substance with low-energy ions is a promising tool for the purposeful formation of such gradient distributions of structural-phase states that provide new properties. New methodological approaches have been developed in the structural analysis of nanoscale materials using synchrotron radiation (with a photon flux density by 12 orders of magnitude, and an exposure duration 150 times shorter than provided by traditional methods of X-ray structural analysis).

The formation of phase composition, structure of FePd, FePt films – magnetic recording media and storage information of high density

Scientific bases of formation nanoscale thermally stable films on the basis of FePd, FePt with hard magnetic L1о phase are created. The new scientific approach concerning application of mechanical stress in nanoscale films on the basis of FePt and FePd for management in temperature of chemical ordering, is offered by formation of phase composition, structure and magnetic properties.

The formation of nanosized hard magnetic FePt films alloyed by Ag, Au, Cu for increase of magnetic recording density

New principles of stable nanoscale hard magnetic FePt films formation with ordered L10(FePt) phase are created by the way of regulation the rate of solid state reactions by using additional layers of alloying elements (Ag, Au, Cu) as regulators of diffusion flows. It is reached the decrease of the hard magnetic L10(FePt) phase formation temperature on 100 K due to extra driving force at the creation of additional interfaces and stress state that accelerate the diffusion processes of ordering.
