Investigation of the influence of kinematic asymmetry on the properties of laminated materials

Abstract. Trend of simultaneous improvement such mechanical metal properties as strength, hardness and ductility remains popular. Asymmetric accumulative roll bonding is a method severe plastic deformation that can create large shear deformations. These deformations in its turn are responsible for increase properties. Initially computer modeling was carried out to study the influence kinematic asymmetry parameters on stress-strain state laminated aluminum composites. For study, combinations alloys 5083/1070, 5083/2024, 6061/1070, 6061/2024 were considered. As result numerical conditions obtaining high values deformation, which affects composites, determined. Experimental confirmation simulation results unique asymmetric rolling mill 400 installed NMSTU. final stage work, development rational technological schemes regimes cold warm composites out. The showed strength plasticity received products, differ ratio total equivalent angles during at least 2 cycles bonding. It shown with an value speed rolls same inter-roll gap, relative reduction increases, force decreases by factor (compared these equal speeds work rolls). supposed use space automotive industries.
