COLLABORATIVE RESEARCH AND DEVELOPMENT (CR&D) Task Order 0039: Topologically Constrained Networks in Metallic Glasses

摘要

This research in support of the Air Force Research Laboratory Materials and Manufacturing Directorate was conducted at Wright-Patterson AFB, Ohio from 18 July 2005 through 29 September 2005. The research applied concepts associated with the Topologically Constrained Network (TCN) model to perform evaluations of the Dense Cluster Packing (DCP) model for metallic glasses. The effort demonstrated that the ABC model has good potential for predicting bulk metallic glass compositions. The model is technologically very useful because all the information needed to calculate glass forming compositions in a system is already available through phase diagrams and crystal structure tables.
