The formation of titanium nitride precipitations during solidification of steel was modeled with own computer software based on Ueshima model. A thermodynamic parameters database was worked out on the basis of literature study. Calculations were performed for two types of steel; one of them was high in titanium. The quantity of produced titanium nitrogen inclusions was calculated. The authors analyzed changes in nitrogen, titanium and oxygen content in the course of segregation of steel components on the solidification front. The influence of solidification rate on the process of precipitation formation was analyzed.

Praca zajmuje się modelowaniem powstawania wydzieleń azotku tytanu w stali podczas krzepnięcia. Zastosowano procedurę obliczeniową z wykorzystaniem modelu Ueshima przy pomocy własnego programu komputerowego. Na podstawie studiów literaturowych przygotowano bazę danych parametrów termodynamicznych. Obliczenia wykonano dla dwóch gatunków stali, z których jeden charakteryzował się wysoką zawartością tytanu. Obliczono ilość powstających wydzieleń azotku tytanu, przeanalizowano zmiany zawartości azotu, tytanu i tlenu w wyniku procesów segregacji składników w stali na froncie krzepnięcia. Zbadano wpływ szybkości krzepniącia na proces powstawania wydzieleń.
