Abstract

In order to examine the grain-boundary migration mechanism, two high purity Fe-3wt%Si bicrystals were produced. One has a (114)Σ9 coincidence boundary, and the other has a random boundary. In-situ observation of grain-boundary migration was conducted by synchrotron X-radiation dynamic topography. It was found that macroscopic grain-boundary migration was recognised at the temperature above 1170K. From the results of isothermal annealing(1270∼1320K), it was clarified that the mobility of Σ9 coincidence boundary was higher than that of the random boundary.
