• The structures of the twin boundary and the stacking fault in body-centered cubic metals have been studied by computer simulation. Particular consideration has been given to the method of the lattice relaxation in order to distinguish more than one stable configuration, if any, of a fault. With the use or the Johnson potential as the interatomic potential, it is confirmed that two types of {112} twin boundaries, the symmetrical boundary and the displaced boundary, are stable. Two kinds of {112} stacking faults, I_1 and I_2, are found. The I_1 fault is stable only under shear stress. The change in the crystal energy is traced in correspondence with the configurational change of a fault. The structures of multilayer faults are also studied.
