| Research Abstract |
The positional distribution of crystallographic orientation in single-crystal nickel-base super-alloy specimens with creep deformation was evaluated by neutron diffraction. The local crystal rotation and the broadening of crystallographic orientation increased gradually with the creep time. The local crystal rotation can be used to specify the damage location before rupture, because the rupture of alloy was generated near the place with local crystal rotation. The possibility in a localization of damage was shown by neutron diffraction that the spatial mapping of the nondestructive measurement was able to be facilitated.
