The experimental results are as follows : (1) When the matrix is deformed only by slip, the coarse grain softens by heating, but it has no new grain by rearrangement. (2) The mechanical twin boundaries are so stable that a single straight twin in matrix revealed no change even after the long time heating. (3) The recrystallized grains are observed at the intersection between a mechanical twin and other twins or a grain boundary. (4) The recrystallized grain has the maximum rate of growth at the direction of mechanical twin boundaries.
