Abstract

Absorbed energy of Charpy impact fracture for the cold rolled 5083 aluminum alloy specimens was investigated mainly in view of the work hardening, related laminated crack formation and effect of the subsequent isothermal annealing treatment etc. Charpy impact fracture testing was achieved for the specimens cold rolled by 30 % reductions of area and subsequently annealed by isothermal heating treatment. Certain side grooved specimens were applied in order to discuss in detail the laminated fracturing behaviors and the absorbed energy.
