| Outline of Final Research Achievements |
This study was aimed at clarifying the mechanism for an irregular rolling deformation, which appears in single crystals of nickel aluminide. We have originally developed a method to quantify the slip systems activated in the irregular rolling deformation, based on the computational crystal plasticity. For three cases of single-crystal rolling experiments we have already reported, we quantified the activated slip systems and compare them with those that should be activated in an ideal rolling deformation, i.e. under the plane strain condition. From the comparison, we identified what slip systems were constraint and proposed a hypothesis that a specific kind of the interaction of slip systems are responsible for this constraint in the nickel aluminide.
