Roslyakova L. I. Thermodynamic Analysis of Equilibrium Condition of Carbon-containing Atmospheres in Nanosized Carbide Structures Formation [Електронний ресурс] / L. I. Roslyakova, I. N. Roslyakov // Журнал нано- та електронної фізики. - 2014. - Т. 6, № 3. - С. 03047-1-03047-2. - Режим доступу: http://nbuv.gov.ua/UJRN/jnef_2014_6_3_49 The paper discusses the processes of the formation of nanosized carbide structures at the interaction of the gas atmospheres components with carbon of <$Ealpha>- and <$Egamma>-solid solutions of iron. Calculations show that the equilibrium content of water vapor in relation to carbon in <$Egamma>-iron under the influence of the increasing hydrogen concentration significantly shifts to the zone of higher values.

Roslyakova L. I. Nanostructure-based Processes at the Carbonizing Steels [Електронний ресурс] / L. I. Roslyakova, I. N. Roslyakov, L. P. Petrova // Журнал нано- та електронної фізики. - 2015. - Т. 7, № 4. - С. 04097-1-04097-3. - Режим доступу: http://nbuv.gov.ua/UJRN/jnef_2015_7_4_99 The studies of nanostructure-based processes carburizing steels showed that oxidizing atmosphere when carburizing steel contains along with carbon dioxide (CO2 + C = 2CO) molecular and atmospheric oxygen (O2 + 2C = 2CO; O + C = CO) released from the carbonate BaCO3 during its thermal dissociation. Intensive formation of CO provides high carbonizing ability of carbonate-soot coating and steel.

Roslyakova L. I. Characteristic Features of Nanoscale Сarbide Inclusions Nucleation and Growth When Carburizing Steels [Електронний ресурс] / L. I. Roslyakova, I. N. Roslyakov, A. G. Besedin // Журнал нано- та електронної фізики. - 2016. - Т. 8, № 3. - С. 03010-1-03010-4. - Режим доступу: http://nbuv.gov.ua/UJRN/jnef_2016_8_3_12 Thermodynamic calculations of the free energy- of the formation of cementite type nanoscale carbides in supersaturated austenite alloyed with chromium and manganese are presented. It is shown that when carburizing steel, chromium stabilizing cementite facilitates its separation, in the form of dispersed inclusions. Manganese stabilizes cementite much weaker than chromium, though facilitates the growth of carbide inclusions due to the formation of the intermediate <$Eepsilon>-phase at a reduced carbon content.
