| Abstract Scope |
Interfacial line defects can serve as point defect sources and sinks. Those that exhibit climb oin the process can mediate strain during process such as Coble creep and densification. These defects are inherently non-equilibrium, and little experimental or computational work has detailed their structure, thermodynamics, or kinetics. This talk will describe efforts to experimentally characterize the energy barriers and activation volumes associated with nucleating strain mediating interfacial line defects using high temperature in situ Coble creep and sintering experiments. |
