Dislocation dissociations in C11b MoSi2 and their impact on its plastic deformation

It is explained why for the [001] orientation of compressive axis the MoSi2 single crystals are brittle at ambient temperature but dislocation glide may occur for compressive loading along different, less symmetrical directions. Non-planar dislocation dissociation on two {013) planes in MoSi2.71
