Two kinetic approaches (integral method and Dybkov method) have been applied for simulating the boriding kinetics of AISI M2 steel in range 1173 to 1323 K, by including effect incubation periods. For integral method, a peculiar solution resulting system differential algebraic equations (DAE) has employed assessing diffusivities boron FeB Fe2B. The activation energies Fe2B deduced from both comp...

SXP 1323 is a peculiar high-mass X-ray binary located in the Small Magellanic Cloud, renowned for its rapid spin-up. We investigate first time broadband properties of SXP1323, as observed by Mikhail Pavlinsky ART-XC and eRosita telescopes on board SRG observatory. Using eRosita, data we produced 1-20 keV spectrum estimated pulsed fraction above 8 keV. With addition archival XMM-Newton observati...

The effectiveness of the process physical education students largely depends on teacher education, one’s competence, pedagogical skills, personal qualities, managerial capacity, and so on. article is devoted to study psychological characteristics a in students. was conducted 2012-2022. 1323 (528 males 795 females) took part research. A survey used their assessment teachers. relationship between...

This work considers phonon entropy effects on phase stability of three binary alloys: Fe-Cr, FeAl, and Al-Ag. In all cases the vibrational entropy plays an interesting role. The phonon density of states was measured on body-centered cubic Fe0.50Cr0.50 prepared as a solid solution, and in increasingly un-mixed states induced by annealing the solid solution at 773 K. Mössbauer spectrometry was us...

To reduce the processing time for in-line carburizing, we performed ultra-rapid carburizing and quenching using induction heating. Conventional gas vacuum (low-pressure carburizing) are treated at 1203–1323 K, which is lower than eutectic temperature. In contrast, in this study, temperature of 1523 K was higher speeding up process. The SCM420 sample rapidly heated to treatment by CH4 N2 were mi...
