Sliding on (011) twist boundaries in copper has been examined below 548 K using Cu-Fe-Co alloy bicrystals with b.c.c. Fe-Co particles on the boundaries. The sliding blocked by the particles has been detected by observing the rotation of moire fringes of the particles in electron microscopy. The temperature dependence of sliding has shown that the sliding of the twist boundaries is slower than that of the symmetric tilt boundaries measured by the same method. There is a good correlation between the ease for a boundary to slide and the energy of the boundary: the larger the degree of the disorder in the atomic arrangement in a boundary, the less resistance the boundary shows to sliding.
