Size Effects in Residual Stress Formation during Quenching of Cylinders Made of Hot-Work Tool Steel

Figure 5

Evolution of tangential surface stresses and phase fractions at position P1 on two cylinders of different sizes (Ø800 mm, Ø100 mm). The small cylinder is quenched from 990°C with gaseous nitrogen at a pressure of 6 bar and the same thermal boundary conditions are applied to the large cylinder.
