The Ti-, S-, and C-containing particles in ultra-low carbon (ULC) interstitial free steels are frequently multi-phase in nature, consisting of TiS (9R) and Ti<sub>4</sub>C<sub>2</sub>S<sub>2</sub>(H), and, therefore, show an irrational Ti/S ratio as detected by an X-ray energy dispersive spectrum (EDS). This paper confirmed the existence of multi-phase precipitates in ULC steels by analytical electron microscopy. It is shown that an accurate description of 9R-H two-phase composite particles can only be achieved when particles are at some special orientations.
