In this paper the interfacial heat transfer coefficient (IHTC) is correlated to applied
external pressure, in which IHTC at the interface between A356 aluminum alloy and
metallic mold during the solidification of the casting under different pressures were
obtained using the Inverse Heat Conduction Problem (IHCP) method. The method
covers the expedient of comparing theoretical and experimental thermal histories.
Temperature profiles obtained from thermocouples were used in a finite difference
heat flow program to estimate the transient heat transfer coefficients. The new simple
formula was presented and compared with data in literature which shows acceptable
agreement.
