Non-classical mechanisms of solid-state precipitation in Ti alloys


The proposed program focuses on novel non-classical mechanisms of solid-state precipitation in metallic alloys, with a primary focus on titanium (Ti) alloys. The significance of the proposed program stems from the interrelationship between microstructure and properties in these alloys where these interrelationships have been determined experimentally. To reduce the time and costs of materials development and optimization, in the future these quantities will be the subject of prediction by computational models. The successful development of such computational models of microstructural evolution depends critically on accurate descriptions of the nucleation process, so that the models may be as physically relevant as possible. Hence, it is the role of the proposed program to provide such accurate descriptions of the factors that influence the nucleation process. (AU)
