Abstract:

The kinetics of formation of austenite in steel 08G2B under continuous heating at a rate of 0.3 and 90 K/sec to the intercritical temperature range is studied with the help of x-ray diffraction, dilatometric and calorimetric methods of analysis. The tests are performed for specimens in two initial conditions, i.e., after recrystallization-free controlled rolling with accelerated cooling and after water quenching from 1000 degrees C. It is shown that the alpha - gamma transformation under the conditions studied may be treated as a diffusion-controlled isokinetic reaction occurring in two stages with rapid formation of austenite nuclei primarily over the boundaries of initial austenite grains.
