The cold-rolled pure titanium film has a rolling texture in which the c-axis is inclined by 30 degrees with respect to the rolling perpendicular direction. After a fatigue test, an active slip plane is identified by using the Electron Back-scatter Diffraction （EBSD） system. As a result, the crack growth rate decreases as the angle between the rolling direction and the load axis increases. The crack growth rate decreases as the angle between the rolling direction and the load axis increases. When a tensile load was applied in the direction of 22.5 degrees or 45 degrees with respect to the rolling direction, prismatic slip was activated, and in the 67.5 degree direction, basal slip was activated. When a tensile load was applied in the direction of 22.5 degrees or 45 degrees with respect to the rolling direction, the slip plane with the highest value of either the Schmid factor or the slip factor of the prismatic slip activated.
