Dynamic Grain Boundary Structure with Gas Inclusions

In see-through experiments of deforming crystals under optical microscopes, it is possible to observe in near real-time processes such as grain boundary migration, fluid inclusion migration and the evolution of grain boundary fluids. These movies are part of the PhD-thesis of Joyce Schmatz (RWTH Aachen University).
In this movie the microstructural process is grain boundary migration recrystallization accompanied by dynamic grain growth. The grain boundary structure is affected by dynamic morphology changes of the grain boundary fluids. Aqueous inclusions are dropped while gaseous inclusions stick to the grain boundaries.
