The mechanical properties of rolled wire-reinforced aluminum composites at different strain values

Abstract The analysis of strain parameters at rolling of aluminum composite with wire-reinforcement was carried out in the present experimental work. The roll bonding of two strips of EN AW-5083 alloy with and without diagonal stainless-steel net-reinforcement between them was experimentally proceeded with different reductions. It is analyzed the influence of the rolling reduction in the range from 25% to 55% on the straining of the wires and composite bonding mechanisms. The present experimental work is established and used the set of describing parameters of the net behavior in the composite such as net cell elongation, wire elongation and wire ovalisation. The means of longitudinal and transversal tensile testing, impact testing and microscopic analysis determine the properties of the rolled composite. The analysis of the rolling reduction influence on the mechanisms of bonding formation in the composite its properties and fracture behavior are carried out. Based on the conducted tests, it was established the optimum range of rolling reductions.
