Joint AOARD/AFRL/LLNL Workshop on the Nucleation of Phase Transformations in Metallic Solids

摘要

A workshop on the Nucleation of Phase Transformations in Metallic Solids was held in Maui, Hawaii on May 2-7, 2010. The meeting was sponsored by the Asian Office of Aerospace Research and Development (AOARD), the Air Force Research Laboratory (AFRL), the Air Force Office of Scientific Research (AFOSR), and the Lawrence Livermore National Laboratory (LLNL). Representatives attended from the United States, Australia, Singapore, India, and France. The focus of the workshop was to develop research tasks aimed at improving current capabilities in the areas of experimentation, modeling and characterization as they apply to the nucleation of solid phase transformations. The overall objectives of the workshop were to bring together a diverse group of researchers to establish the state of the art in experimenting, characterizing and modeling. Specifics items addressed included (1) what advances are needed in the atomistic/computational modeling area to significantly impact the science; (2) what tools and techniques are required to characterize the formation of nucleants and the local chemical and energy environment; and (3) what opportunities exist for combining advance characterization techniques with experimental validation of nucleation models. The results are provided within this document, including the presentation materials from participants.
