In a career spanning almost six decades, Prof. John T. Berry has made significant contributions towards building our understanding of solidification and process-structure-property relationships in shaped castings. Celebrating his contributions, the Fourth International Shape Casting Symposium, which takes place at the 2011 TMS Annual Meeting & Exhibition, has been organized in his honor. Shape Casting 2011 contains the proceedings of the symposium in which scientists and engineers from around the world presented their own research findings, discussed challenges in the field, and projected future directions. Papers explore such topics as liquid metal quality; filling and feeding systems; process modeling for shaped castings; structure-property relationships; performance of shaped castings; and machinability of castings.
