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). This movie shows deformation of polycrystalline camphor with ethanol at 70 °C with a constant strain rate of 2.6 x10-6 s-1, the microstructural process is grain boundary migration recrystallization. One and the same fluid inclusion (red arrow) is passed by three different, presumably fluid-filled grain boundaries. For further information see our articles: http://onlinelibrary.wiley.com/doi/10.1111/j.1525-1314.2009.00849.x/abstract and http://www.springerlink.com/content/g6183047l556118k/ . Joyce' MOVIE of the week (CW 8, 2011)
I don;t suppose anyone has read the FEMA report on 9/11, the part on grain boundaries is very interesting
