【Abstract】 The mechanical properties of Nb-microalloyed high strength steel after cold rolling can be improved by recrystallization annealing.The annealing experiments were carried out under different heat treatment parameters,and then the annealed structure was measured to figure out recrystylization.Based on the measured properties data of the samples,the mathematical models were set up between annealing parameters and properties,which can be used to predict the properties of the annealed steel and control the annealing procedure in the production.更多还原
