Abstract

Compression tests were conducted in order to study the static recrystallization kinetics of hot deformed austenite in hypereutectoid steels containing 1% carbon with different levels of vanadium and silicon. Tests were performed over a temperature range of 875 to 1100°C using strain rates of 0.01, 0.1 and 1 s−1. Graphs of the recrystallized fraction versus time were used to quantify the kinetics of the strain-induced precipitation and generate the precipitation temperature time diagrams for the three steels. A kinetic model for static recrystallization is proposed which takes the V and Si concentrations into account.
