A nonuniform  contact pressure between the casting and the mold                 during the solidification process can result in a casting surface               with wavy defects as well as undesirable residual stresses.  The                latter could cause spontaneous failure of the casting at a later                date.  Dr. J. R. Barber will use measured contact resistance and                contact pressure between the casting and mold to study the                      solidification process.  The related experiments will be conducted at           ALCOA Research Laboratory at no cost to this award thus demonstrating           its industrial significance.  This study should lead to optimum                 material properties and mold cooling strategies for a better surface            finish and minimum residual stresses in a casting.  Dr. Barber is               most qualified to undertake this interdisciplinary research involving           solid mechanics and heat transfer.  Dr. O. Richmond, ALCOA, will                conduct the experimental studies and participate in the theoretical             studies.  Also  Dr. A. Azarkhin, ALCOA, wail be an advisor and an               active participant in the theoretical studies.
