Abstract
The Ti-, S-, and C-containing particles in ultra-low carbon (ULC) inte rstitial free steels are frequently multi-phase in nature, consisting of TIS (9R) and Ti4C2S2 (H), and, therefore, show an irrational Ti/S r atio as detected by an X-ray energy dispersive spectrum (EDS). This pa per confirmed the existence of multi-phase precipitates in ULC steels by analytical electron microscopy. It is shown that an accurate descri ption of 9R-H two-phase composite particles can only be achieved when particles are at some special orientations.
