Abstract
The growth of bicrystals containing high-energy grain boundaries is documented by the 45 ∘ [ 1 0 0 ] , { 0 k l } symmetrical interface in an Fe–Si base alloy. During the bicrystal growth by the floating zone technique, this general grain boundary tends to rotate along the sample axis thus changing its original orientation into an energetically more advantageous one. A detailed investigation of the dislocation and subgrain structures in the vicinity of the inclining grain boundary proves that other reasons for this continuous inclination are excluded.
