The results of the studies of phase formation and the structural state of diffusional zinc coatings formed in zinc powder with nanocrystallized surface of the particles are presented. The sequence of iron-zinc phases formation during the process has been established, which is the reciprocal of those obtained during the annealing of "hot dip" coatings. The microstructure of δ-phase in the coating, a change in its texture and structural parameters through the thickness of the coating have been studied.

The deformation behavior of supermartensitic and martensitic stainless steels was investigated through compression test using Gleeble-3800 thermo-mechanical simulator within the temperature range of 900 – 1200 оС and the strain rates range of 0.01 – 10 s-1. The results showed that the flow stress and the peak strain increase with the drop in the deformation temperature and the rise in the strain rate. Flow stress of SMS steel exceeds flow stress of MS steel for same regimes of deformation. The difference in flow stress increases with the increase in Zener-Hollomon parameter, but does not exceed 15 MPa. The critical deformation, required to start dynamic recrystallization, for supermartensitic stainless steel is slightly lower than for martensitic stainless steel. The hot deformation activation energy of steels is also investigated, their values are similar and equal to 432 and 440 kJ/mol for MS and SMS steel, respectively.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
