摘要

The mechanical properties and development of microstructure and texture of a low carbon steel produced by Flexible Thin Slab Rolling (FTSR) with warm rolling technology were investigated using scanning electron microscopy, transmission electron microscopy and electron back-scattered diffraction. The microstructural features in the hot strip are mainly big polygonal ferrite grains with very little or hardly any pearlite colonies. Random and weak {110}< 112 > transformation texture was examined in the final microstructure by electron back-scattered diffraction. By analysis, the ferrite softening can be attributed to ferrite recrystallization, and the large grain size is explained in terms of ferrite recrystallization and relevant growth mechanisms. The ferrite recrystallization can be considered to play the major role in determining the grain size in the microstructure of low carbon steel produced by FTSR with warm rolling technology.
