| Outline of Final Research Achievements |
The objective of this study was to clarify the plastic deformation behavior of beta-Ti alloys which have been developed as a new Ni-free shape memory alloy. To systematically investigate the plastic deformation behavior of martensite phase, the single crystalline martensite was fabricated in this study. Four operative plastic deformation modes were observed: (1) {130} twin, (2) {103} twin, (3) <110> slip and (4) <101> slip. These plastic deformation modes in martensite phase corresponds to the {332} twin and <111> slip in the parent beta phase.
