Abstract
A model steel microalloyed with vanadium is studied in detail for features of the change in microstructure, mechanical properties, and nanosize carbonitride precipitates in relation to hot rolling parameters. It is established that grain size decreases uniformly and its stretching increases with a reduction in temperature for the end of rolling. The set of steel mechanical properties is decisively affected by the system of nanosize vanadium carbonitride precipitates, including precipitates of three types: interphase, formed during γ→α transformation, and also generated within austenite and formed within ferrite during wound coil cooling.
