Abstract

The experimental techniques for crack velocity measurements have been applied to bicrystals of tungsten with twist orientations about «100» and polycrystals. The hesitation of the propagating cleavage crack in the vicinity of the grain boundary is examined. The contributions to energy dissipation from deformation and fracture processes in the grain boundary region as well as the indirect effects of crack deceleration are discussed. These findings have been applied to explain the dynamic fracture resistance and crack arrest in polycrystals.
