Abstract


An important feature of aluminium killed steels is the strong influence that aluminium nitride precipitates produce in both the mechanical properties and the final microstructural characteristics of the steel. This influence is related to the different stages of the fabrication process. This paper deals with a study of the effects of aluminium nitrides on the kinetics of recrystallisation. Different heat treatments were carried out, in one case to dissolve AIN, and in the other in order to precipitate AIN. These steels were subjected to cold rolling, followed by a batch annealing process. The recrystallised fraction was measured, thus obtaining the kinetic curves. The activation energy for recrystallisation was computed in each case. The results showed that AIN precipitation during recrystallisation produces a delay in recrystallisation kinetics through a change in the activation energy value.
