title = "Mixed mode crack tip deformation in lamellar TiAl mapped by digital electron speckle photography",
abstract = "Brazilian disk specimens made of lamellar TiAl were tested under compression with the central crack oriented at different angles with respect to the loading direction. Micron and sub-micron sized speckles made of gold were created onto the specimen surface via a physical vapor deposition process. The specimens were tested in the vacuum chamber of a scanning electron microscope. Electron speckle images of the specimen under different stages of loading were recorded digitally and processed through an algorithm called CASI (Computer Aided Speckle Interferometry). Full field deformation patterns were obtained showing the characteristics of the crack propagation in TiAl under mixed mode loading conditions.",
