AF lab investigating microscopic crack formation for aircraft
Dr. Adam Pilchak, a materials research engineer with the Air Force Research Laboratory, loads a piece of a fractured titanium disk into a scanning electron microscope at Wright-Patterson Air Force Base, Ohio. By looking at the microscopic features on the fracture surface, researchers are able to determine how the crack initiated and spreads through the component to cause the failure.
