Nanoindentation is widely used to investigate elastic modulus, hardness and work hardening behaviour of nano- micro-scale laminates. In this work, 16 nm accumulative roll bonding (ARB) Cu/Nb nanolaminate as a test material due its interfacial anisotropy owing the presence contrasting interfaces along rolling (RD) transverse direction (TD). was performed TD well RD ARB nanolaminate, then scannin...

This paper deals with modeling and optimization of the roll-bonding process of Ti/Cu/Ti composite for determination of the best roll-bonding parameters leading to the maximum Ti/Cu bond strength by combination of neural network and genetic algorithm. An artificial neural network (ANN) program has been proposed to determine the effect of practical parameters, i.e., rolling temperature, reduction...

Accumulative roll-bonding (ARB) is a severe plastic deformation process that is using rolling to produce ultrafine grains in coarse grained metallic materials. In this study, ARB has been applied on 70/30 brass up to 6 cycles at ambient temperature and non-lubricated conditions to apply a true strain up to 4.8 Von Mises strain. Microstructures of ARBed brass samples were characterized by scanni...

This paper aims to investigate the properties of aluminum-based composite Al2O3/SiC ceramics using new severe plastic deformation (SPD) methods and finite element method. research work also focused on accuracy simulation results in manufacturing reinforced ceramic. The latest method was developed by repetitive press-roll forming (RPRF) for processing ceramic-reinforced materials. simulations we...

Copper is one of the first metals to ever be mined and used by humans, since dawn civilization, it has made important contributions behavioral science. The exploration copper provided knowledge nonfuel minerals consequently improved society. objective this paper investigate effect annealing on microstructure, mechanical properties, corrosion material before undergoing an accumulative roll bondi...
