The change of structure in final high temperature rolling niobium microalloyed steel strip

The interaction mechanisms of precipitation, hardening through plastic deformation and softening trough recover or recrystallization and final thermomechanical treatment of niobium microalloyed steel strip were studied. For that purpose these methods are used: metallographic microanalysis and x- ray diffraction analysis. On the all samples have been measured of precipitation degree The obtained results at the analysis in the every phase final thermomechanical treatment like: grain size, the hardness and the back reflection patterns Debyes rings of Fe showed the changes.
