| 摘 要： | The carbides/nitrides precipitates in ferrite grains, on grain boundaries and dislocations were investigated on a hot-rolled C-Mn strip （0.16wt%C-1.22wt%Mn-0.022wt%Ti） produced by the CSP （compact strip production） technology using TEM and X-ray energy dispersive spectroscopy. The Pickering＇s equation for the contribution of precipitates to the yield stress was also discussed. It is shown that there are numerous fine and dispersive precipitates TiC in the ferrite grains, on the grain boundaries and dislocations. Also there are a small amount of coarser Ti（C, N） particles and TiC particles associated with MnS. Precipitation strengthening on steels produced by the CSP technology is significant.
