Analysis on Dislocation Morphology and Dislocation Densities of Hot Strip of Low Carbon Steel Produced by CSP

The dislocation and morphology dislocation density in the hot strip of low carbon steel after finishing pass produced by CSP were investigated by using H-800 transmission electron microscopy and positron annihilation technology. The experimental results showed that the dislocation density increased with the cumulative reduction increased. The dislocation density after the finishing pass is larger than that of the hot strip produced by the conventional technique.
