Warm forging of steels, in the range from 600 to 900 C, offers some important advantages over traditional forging procedures, with a better dimensional accuracy as well as surface quality in comparison with hot forging, and lower flow stress and therefore lower press loads in comparison with cold forging. It is well established that in hot working of V microalloyed steels, the vanadium in solid solution has a little effect on the static recrystallization kinetics between passes. In contrast, if strain induced precipitation takes place the static recrystallization is notably modified. The objective of this work is to study the effects that the application of warm working can have on the austenite static recrystallization process of vanadium microalloyed steels, considering a range of temperatures in which different precipitate volume fractions can remain undissolved in the austenite prior to deformation. The static recrystallization kinetics were determined by stress relaxation tests following the deformation by plain strain compression.
