Abstract
In order to clarify the crack morphology in 180° bend-forming of the TiN film deposited on (011) [100] single crystals of silicon steel, TiN coating by the hollow cathode discharge (HCD) method was done on a polished (011) [100] single crystal sample. The TiN-coated samples were 180° bend-formed and observed by the scanning electron microscope.<BR>In the position (a) just above 180° bend-forming, TiN film showed the straight crack at the interval of 2-4 μm parallel to the direction of [121] TiN. In contrast, in the position (b) near the transition zone from bend-forming to tensioning, TiN film showed an elliptical morphology 23-30 μm long and 9-12 μm wide.<BR>The point of origin of a small TiN crack can be seen near the center of the ellipse, and the straight crack in the TiN film will propagate from this origin.<BR>It should be noted that the TiN crack morphology differed remarkably depending on the positions of bend-forming.
