Prediction of Stable Nanocrystalline Binary Alloys

Problem: Need for general framework to design new nanocrystalline alloys that are stable against both grain growth and phase separation, both critical to commercialization of products with long lifetimes. Technology: This invention presents the first model for the design of nanocrystalline alloys that are stable against both grain growth and phase separation. This model can be used to identify many viable alloy systems that can be made in a stable nanocrystalline form. The model generates a nanocrystalline phase behavior map that can predict the existence of a stable nanoscaled microstructure in phase-separating binary alloys. Christopher Noble crn@mit.edu
