    Atomic planes at three different positions ABC form the stacking along the 111 directions in the FCC lattice and similarly along the 0001 hexagonal axis in the C40 structure in transition metal silicides. However, the structures of suicides are constituted of several stacking of identical atomic planes at four different positions: AB in C11(b) structures of e.g. MoSi2, ABC in C40 structures of e.g. VSi2 and ABDC in C54 structures of e.g. TiSi2 disilicides. The occurrence of the fourth position essentially influences the properties of defects and consequently the mechanical properties of C40 materials.
