Abstract
As metalforming processes are intensified, heat treatment assumes a greater significance. An important role is played in this respect by methods of accelerating recrystallization, based on increasing the rate of heating to relatively high temperatures so that the whole process takes only a few seconds. Such changes in the heat-treatment parameters should influence material properties and the mechanisms of the recovery process. Based on tests on Cu-30Zn brass, the influence of the heating rate (up to 400KS−l) on static recrystallization was studied. Results arepresented in terms of the relationships between heat-treatment parameters, grain size, and mechanical properties. The influence of heating rate on the isochronal recovery state was also studied.
