New Developments in the Brittle to Ductile Transitions of Fracture in Intrinsically Brittle CrystalWe will briefly review some recent developments in the study of the brittle to ductile transitions in fracture in some intrinsically brittle crystalline solids both on the experimental and theoretical level or with computer modeling.

Cross Slip Viewed at the Nano- and Micrometer Scale, emphasis on the activation energy for cross slip. The results are compared with observations of the texture transition in brass and with microstructural observations on cyclically deformed copper. The indication is that cross slip plays a governing role in texture formation and in cyclic deformation/fatigue.

Experimental Investigations of Size Effects in Thin Copper Foils,are performed with specimens, which possess a comparable microstructure, a constant thickness/width and width/length ratio whereas the thickness varies from 10 to 250 µm. Results show a transition from ductile to a macroscopically “brittle” behavior in the range of about 20 µm.
