Abstract

Effects of second phase particles on the tensile deformation and fracture behavior of the commercial 5083 aluminum alloy plates at -196°C and at room temperature were discussed.
According to the results, the initiation of the voids in the process of tensile deformation and fracture, three types of behavior were observed, such as, (a) initiation of void due to separation of the interface between the second phase particles and matrix phase, (b) fracture of second phase particles, (c) separation of the grain boundary.
It appeared that such voids as initiated from rectangular form particles of Al₆(Fe, Mn) tended to positively grow to the crack formation and propagation.
Occurrence rate of fracture of second phase particles was increased with the increase of plastic strain. The maximum ratio of fracture of second phase particles to the plastic strain was observed in the tensile deformation at -100°C and slightly decreased at 0°C. The lowest ratio of fracture of the particles was observed at -196°C.
