Question

The crack may be
and
depending on strength of grain boundaries.?
Brittle, ductile
Trans granular, intergranular
Shear, cleavage
Fibrous, granular​

Answer 1

Answer:

These features also depend on the response of the material to deformation processing ... As strength increases, ductility and fracture toughness usually decrease. ... (a) Transgranular fracture through the grains and (b) intergranular fracture ... grain boundary phase and is of the intergranular fracture-type, cyclic fatigue crack ...
