Translation of "Cleavage fracture" in German

This curve plot exhibits a clear transition from deformation fracture to cleavage fracture as temperature decreases.

In the case of transcrystalline cleavage fracture, the crack runs transversely through the grain.

At 170 K, the specimen width has hardly any influence on the stresses, the specimens fractured ,following slight plastic deformations and a small proportion of ductile crack growth , by an unstable propagated cleavage fracture (Fig.I.31).

At low temperatures,these steels show an undeformed cleavage fracture, at high temperatures, a fully ductile behaviour with slide fracture.

Accordingly, at tool speeds below the critical speed v k the material will fracture more readily by deformation fracture (i.e., ductile fracture) than by cleavage fracture.

At temperatures above the critical temperature T k material failure occurs primarily due to ductile fracture, while, by contrast, below the critical temperature T k material failure occurs primarily due to brittle fracture (i.e., cleavage fracture).

This ensures that, after the microstructure is created (first working), surface roughness O is reduced, especially by cleavage fracture.

It should be mentioned, however, that the microstructure of the materials used has grains preferably in the nanometer range, and therefore even in the case of intercrystalline cleavage fracture there will be roughness only in the nanometer range.

If the structure should have grains in the micrometer range, then in any case transcrystalline cleavage fracture is desired.
