Ductile and brittle fracture are distinguished by the condition of the fracture surface. A typical example of brittle fracture is the absence of traces of plastic deformation on the fracture surface. For all metals, especially bcc and hcp and even fcc metals (with the exception of copper and nickel), a change in the fracture mechanisms is observed (the threshold of cold brittleness) which is a characteristic sensitive to structure and composition. The transition to the brittle condition is an attribute of the crystal lattice and is probably due to an increase in the percentage of covalent bonds with decreasing temperatures.
