ResumenBy means of torsion trials, the influence of various alloying elements on the parametert 0.5 of Avrami's equation has been studied. It has been found that carbon accelerates the static recrystallization of the austenite and that the other elements, in solution or by forming precipitates, slow it down. It is verified that the activation energy is the parameter most sensitive to the chemical composition and its value has been defined in a collection of 11 steels of the C-Mn type and those, microalloyed with Nb and Ti. Finally an equation is proposed which allows the calculation of the activation energy as a function of the chemical composition of the steel with great accuracy.
