Among others the following results were attained: the transcrystalline ductile fracture of copper and some of its alloys resulting from a considerable plastic deformation, with numerous dimples, in the middle of which there usually appear second phase inclusions. — Intercrystalline fracture due to cracks along the grain boundaries may be different, sometimes scarecely to be disguished from the transcrystalline cleavable fracture. It should rank among brittle fracture as its appearance is always characterized by considerable brittleness of the material. Brittleness of copper and its alloys result from precipitations of these phases on the grain boundaries. |
