LATTICE DISTORTION STORED ENERGY OF CRYSTALLOGRAPHIC ORIENTATIONS IN COLD-ROLLED LOW CARBON STEEL SHEETS

The order from big to small of lattice distortion stored energy of main crystallography orientations of cold-rolled low carbon steel sheets has been argued for a long time. In order to provide information for investigating re-crystallized mechanism, lattice distortion stored energy of 13 orientations of 74.5%-88% relative draught cold-roll samples with different process and composition are measured by X-ray analysis technique. The result shows that lattice distortion and its stored energy of crystallography orientations depend on their Young′s modulus and cold-rolling relative draught. The order of stored energy of main orientations is γ100>γ110>γ112>γ111 as relative draught is lower, and γ110>γ100>γ112>γ111 if it upper to 77%-88%.
