Title: Processing and mechanical properties of laminated metal composites of Al/Al-25 vol. % SiC and ultrahigh carbon steel/brass

Abstract

Al 5182/Al 6061-25 vol.% SiCp and ultrahigh carbon (1.8% C) steel/brass (70% Cu-30% Zn type) laminates were prepared by press-bonding stacks of alternating layers of the component materials. Press bonding of these materials required consideration of the flow stresses of the component materials and the interlayer friction. Tensile properties and fracture toughness were measured for different processing conditions of surface oxide descaling, layer thickness, and heat treatment. Descaling of the surface oxide prior to the press-bonding was found to eliminate premature delamination along interfaces resulting in an increased yield strength and tensile ductility. Reduction in the layer thickness brought an increase in the tensile ductility for both laminates, a decrease in yield strength and fracture toughness for the Al laminate. T6 heat treatment on the Al laminate induced a substantial increase in the yield and tensile strength but a decrease in tensile ductility. Fracture surface morphology indicated evidences of local delamination, crack blunting and bridging. Fracture toughness measured in the crack arrester and crack divider orientation showed a substantial enhancement over that of the Al 6061-SiCp or UHCS components.
