Abstract
An optimization-based numerical procedure was developed to determine the pressure-dependent heat transfer coefficient (HTC) between the blank and tools during the hot stamping of boron steel. During the quenching period, HTC increased with the contact pressure between blank and lower tool. There is no obvious linear relationship between them. The maximum value of 1500 W/m2 K was achieved at contact pressure 18 MPa.
