Abstract

An optimization-based numerical procedure was developed to determine the temperature-dependent interface heat transfer coefficient (IHTC) between blank and tools during the hot stamping of boron steel. During the quenching period, IHTC changed with the temperature difference between blank and lower tool. The maximum value of 4300 W/m2 K was achieved at ΔT = 798 K (525 °C). The IHTC decreased with temperature difference and reached the lowest value (1400 W/m2 K) at about ΔT = 573 K (300 °C).
