Abstract

The present study introduces a new experimental setup for the accurate measurement of interfacial heat transfer coefficients during hot stamping with focus on an appropriate temperature measurement. For the evaluation of measurements with varying quenching start temperatures and pressures for the blank material 22MnB5 coated with 150 g⋅m2 of Al-Si, Beck’s regularization method has proven to be most reliable, whereas the energy conservation method is associated with difficulties in a correct description of the release of phase-transition enthalpies in the blank. For quenching experiments performed at an insert temperature of 700 °C and pressures between (1.0 and 18.7) MPa, the time-averaged and maximum values of the measured interfacial heat transfer coefficients ranged from (3.0 to 6.0) kW⋅m−2⋅K−1 and (8.1 to 9.5) kW⋅m−2⋅K−1, respectively. The obtained results indicate that the setup is applicable for future studies aiming at systematic investigations of factors influencing interfacial heat transfer during hot forming.
