Abstract Scope |
Examples will be used to illustrate the effectiveness of dual-anneal diffusion-multiples (DADMs) in systematically studying phase precipitation and microstructure evolution. Wide ranges of compositions of solid solutions are generated in diffusion multiples by a long-term, high-temperature anneal. Subsequent precipitation anneal at lower temperatures for different durations results in the formation of various precipitates across wide composition regions. Systematic examinations of precipitate morphologies and evolution as a function of composition as well as time and temperature provide very large amount of experimental information on precipitation kinetics. The atlases of microstructures and their evolution across the compositions can provide big, multimodal datasets on phase precipitation to test model predictions and to find new approaches to improve the models. Results on the phase precipitation and microstructure evolution in the Fe-Cr-Ni and Fe-Cr-Mo systems will be presented in detail. |
