| 摘 要： | Electron microscopic investigation on low carbon steel strips produced by the CSP process has been carried out.Large number of oxide dispersive precipitates have been observed in the ferrite matrix of the steel strips.Dimension of them is about 10-20nm.Electron diffraction study showed that the structure of these precipitates consists with cubic system spinel structure .Their lattice parameter is about 0.83nm.The results implied that they should be complex oxides of Fe,Al et al.Small sulfide particles with 100-300nm in size have also been observed.Remarkable strengthening and grain refinement effects can be obtained by the precipitations.The oxygen and sulfur in steels could play beneficial role under certain conditions.

| Abstract: | Electron microscopic investigation on low carbon steel strips produced by the CSP process has been carried out. Large number of oxide dispersive precipitates have been observed in the ferrite matrix of the steel strips. Dimension of them is about 10~20 nm. Electron diffraction study showed that the structure of these precipitates consists with cubic system spinel structure. Their lattice parameter is about 0.83 nm. The results implied that they should be complex oxides of Fe, Al et al. Small sulfide particles with 100-300 nm in size have also been observed. Remarkable strengthening and grain refinement effects can be obtained by the precipitations. The oxygen and sulfur in steels could play beneficial role under certain conditions. |
