Not Available Unanticipated distortion during the heat treatment of precision steel parts adds significant cost for both commercial and defense suppliers. A collaborative project managed by the National Center for Manufacturing sciences has resulted in the development of a multiphase internal state variable material model and comprehensive phase transformation kinetics models that accurately describe the mechanical and metallurgical response of steel alloys to carburization and immersion quench hardening processes. Other significant progress was made in process characterization and in describing heat transfer between the workplace and environment. This capability will be extended to include fixtured and press quenching. A commercial software tool to predict dimensional change, residual stresses, metallurgical phase distribution and volume fraction, and hardness of both through-hardened and carburized steel parts that have been heat-treated will be developed. The user interface of the software will be a customized version P3/PATRAN that contains dataforms specific to the heat treat industry. The software will produce finite element models to be solved using ABAQUS and it's user defined material subroutine capability. Included in this software development program is the specification of the material and process data required for simulation and the methods for determining these data. BENEFITS: The commercial application resulting from this project is a software tool to sell to heat t
