摘要: Results of investigation into the destruction Ni3Ge single crystals oriented along [001] axis are presented. Dislocation structures and deformation relief after at different temperatures studied. It is demonstrated that dislocation structure remains homogeneous in entire range anomalous temperature dependence mechanical properties. Transition from brittle to brittle-viscous mechanism observed with increasing temperature. Zones completely or partially destructed long atomic order formed near opened crack surfaces.
