A possibility to control the strength, hardness and ductility of the L35HM low-alloy structural cast steel by the applied tempering temperature is discussed in the paper. Tests were carried out on samples taken from the two randomly selected industrial melts. Heat treatment of the cast samples included quenching at 900°C, cooling in an aqueous solution of polymer, and tempering at 600 and 650°C. The...
Badano szybkość krystalizacji sacharozy w temperaturze 50°C z roztworów czystych o przesyceniu 1,1. Roztwory te poddawano przed krystalizacją wygrzewaniu w temperaturze 90°C. Wygrzewania prowadzono w zakresie od 0 do 90 min. Maksimum szybkość i krystalizacji wystąpiło przy 20-minutowym czasie wygrzewania. Może to świadczyć o występowaniu optymalnej wielkości pakietów wbudowujących się w siatkę krystaliczną.
