Inhomogeneous Deformation of Multilayered Roll-Bonded Brass/Cu Composites

Abstract

The deformation gradients in multilayered hot roll-bonded composite materials incorporating two dissimilar face-centered cubic metals, i.e., brass and Cu, were investigated by characterizing the deformation microstructure, hardness and texture at different thickness positions of the composites. For the constitutive metals, the center part of each metal sheet forms the substructure containing coarse grains, while the ultrafine grains and significant shear banding form in the outer part. As deformation increases, the cross-interface shear occurs in the Cu sheet of the composites. Then, grain fragmentation, shear banding and dynamic recovery become the main factors that influence hardness of the metal. Moreover, in the co-deformed composites, the interface between brass and Cu plays a role in texture developments of the individual metals.

On the Structure and Mechanical Properties of Multilayered Composite, Obtained by Explosive Welding of High-Strength Titanium Alloys

“…There are several technologies for the fabrication of laminated composites. For instance, roll bonding [10][11][12][13][14][15] and diffusion (reaction) bonding [12,16,17] have been known for a long time. In several studies (e.g., [18,19]), an explosive welding technique has been proposed for fabrication of laminated composites.…”

An Easy Way to Quantify the Adhesion Energy of Nanostructured Cu/X (X = Cr, Ta, Mo, Nb, Zr) Multilayer Films Adherent to Polyimide Substrates

“…Nanostructured multilayer films (NMFs) have a large number of potential applications, such as a variety of structural uses and microelectromechanical systems (MEMS), due to the ease of tailoring mechanical properties [11][12][13][14][15][16][17][18] and some novel physical properties such as transport properties [19][20][21]. Nevertheless, evaluation of the interfacial adhesion of NMFs on compliant substrate is still unavailable.…”
