Abstract
Studying the behavior of the impact of nanodispersed refractory particles Ti(CN) on the structe of the modified Si-Mn – steels. Plasma-chemical synthesis method was nanoparticulate powder com-posites Ti(CN) fraction under100 nm. Calculated specific surface area of the powder compositions in the study of the structure and size parameters of nanocomposites, applied modern methods of electron microscopy, thermodynamic analysis. An ana-lytical review of the problem of receiving construction materials containing nanosized composites. Calculate the size of Ti(CN) powders, their specific surface area and specific surface energy. Definitely the optimal size on the nanoparticles. Thermody-namic calculations of change in the free energy of the system and the surface. The optimal number of nanoparticle Ti(CN) size 20–40 nm are centers of melt by crystallization. Proposed and theoretically justified the use of nanodispersed composition Ti(CN) 20–40 nm size as modifiers steel 16ГС. The conditions of thermodynamic stability of the system «nanoparticle metal». The optimal amount of na-nosized modified Ti(CN) for the treatment of steel 16ГС – 0,10 % by weight. Grinding grain castings reachas 2–3,5 times. The technological instructions for modifying Si–Mn-steels nanocomposite for ex-perimental-industrial testing at metallurgical plants.
