Modeling of TiN and Ti2O3 Precipitates Formation During Solidification of Steel/ Modelowanie Powstawania Wydzieleń TiN I Ti2O3 W Procesie Krzepni?cia Stali

摘要

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.
