The aim of the paper was to investigate helical rolling parameters (a number passes) for microstructural modification and low-temperature impact toughness improvement 09Mn2Si High Strength Low-Alloyed (HSLA) steel. In order achieve this purpose, work spent crack initiation propagation analyzed compared with patterns fracture surfaces. microstructure values were presented in temperature range fr...

Carbide precipitation in martensitic low alloyed steels contributes to the mechanical properties through hardening. A high number density of carbides is desired maximize hardening effect, which achieved on dislocations structure. In this study, nucleation, growth, and coarsening vanadium molybdenum during aging at 600 °C for periods up four weeks were investigated. The work covers characterizat...

Martensitic and nanobainite transformations are studied in situ a low alloyed, high-Si steel by using HEXRD, combined with dilatometry SEM observations, considering the same composition austenitization conditions. The martensitic microstructure presents mixed lath-plate morphology large scatter of sizes whereas bainite shows finer laths more uniform sizes. Recently introduced methods used to tr...

The study results of the structure and properties layer deposited with flux-cored wires Fe-C-Si-Mn-Cr-Mo-Ni system additionally alloyed titanium are presented. Surfacing investigated was carried out on a substrate made 09G2S steel using silicomanganese slag flux.
