SUMMARY:MSE Seminar: “Advanced Microscopy Techniques for Understanding Dislocation Interactions & Damage in Complex Microstructures”
DESCRIPTION:Microstructurally and compositionally complex alloys (MCCA) such as Nickel-Aluminum-Bronze (NAB) are important to Navy and maritime applications due to their high strength\, toughness\, and fatigue resistance\, as well as excellent corrosion resistance. NAB’s are widely used in many naval applications including ship propellers\, underwater fasteners\, pumps\, and valves. Traditional sand cast NAB alloys tend to have a large amount of waste material\, and reduced complexity in component geometry due to the limitations of the casting processing.  As a result\, NAB alloys are emerging as a viable alloy for additive manufacturing (AM) and therefore provides a new space to establish fundamental relationships between AM processing\, structure and properties. Of the additive processes\, wire arc additive manufacturing (WAAM) is an evolving technology for fabricating large-scale\, near net shape NAB components. It is understood that the high cooling rates achieved in WAAM prevent the precipitation of coarse rosette-like kI phase which usually form during the latter stages of solidification during the casting process. In this work\, the dislocation interactions with interfaces such as grain boundaries and precipitates will be used to understand fatigue life and crack initiation and growth behavior in these alloys during low-cycle and high-cycle fatigue.
