OPTIMIZATION OF THE STRUCTURE AND PROPERTIES OF HIGH-STRENGTH MICROALLOYED STEEL ROLLED PRODUCT IN RELATION TO DEGREE OF COLD DEFORMATION

摘要

The effect of small degrees of reduction on the properties of high-strength microalloyed steel cold-rolled product are studied. Features are established for rolled product structure and property formation in relation to chemical composition and production parameters. Production recommendations are developed providing the highest set of rolled product properties for the steels in question. Production processes developed on the basis of established features are approved under industrial manufacturing conditions.
