Evolutionand formation of Ti-bearing inclusions in AISI 321 stainless steel in ignoring casting process was investigated. The industrial test results show that titanium oxidation occurs after Ti addition in LF process and the proportion of Ti

the stable diagram of Ti- Al-0 and Ti-N in the liquid steel and precipitation of TiN during solidification were also calculated by thermodynamic software Factsage.
