Abstract
According to the part 1 of this work, in this second part the dynamic recrystallization of a commercial medium carbon microalloyed steel is characterized from the point of view of its onset and kinetics. For this purpose uniaxial hot compression tests were carried out over a range of five orders of magnitude in strain rate and 300 °C of temperature. Experimental results are compared with those reported in the literature and the possible effect of dynamic precipitation is also analyzed. It is verified that the kinetics of dynamic recrystallization can faithfully be described by the classical Avrami equation.

Summary
Los aceros microaleados con un contenido medio de carbono han venido aumentando su campo de aplicación en la industria de la automoción (1 y 2). A pesar de que las características de resistencia obtenidas son suficientes en la mayoría de los casos, no ocurre lo mismo con la tenacidad, que persistentemente muestra valores escasos. Una de las formas de mejorar la tenacidad en estos aceros pasa por el mantenimiento u obtención de un tamaño de grano austenítico fino. La determinación de las ecuaciones constitutivas (ya planteadas en la I parte de este trabajo) y su relación con el tamaño de grano producido se convierte en una necesidad, especialmente en el caso de aceros de forja. Además, la simulación de los procesos de fluencia por métodos numéricos, y proporcionarán a la vez una optimización de los mismos.
