In this research, Al-Ni particle composite strips are formed by accumulative roll bonding (ARB) process using Al strips and Ni powder. The rule of ARB cycles and volume percentage (Vol%) of Ni powder on the microstructure, wear resistance and mechanical properties of the formed composites are investigated. According to the tensile test results, the yield stress and tensile strengths of the Al -...

Nanostructured Cu-/Al-laminated composites were processed by accumulative roll-bonding (ARB) technique for four cycles. Microstructural evolutions inside the Cu and Al layers interfacial reactions revealed after annealing at different temperatures. Recovery recrystallization occurred in low temperatures, three kinds of intermetallic compounds formed near interfaces. The mechanical properties th...

A new computational method based on MATLAB was used to study the effect of different parameters on the homogeneity of composites produced by a severe plastic deformation technique known as accumulative roll bonding. For a higher number of passes, the degree of particle agglomeration and clustering decreased, and an appreciable homogeneity was obtained in both longitudinal and transverse directi...

techniques of severe plastic deformation have been successfully used for the production of novel metallic microstructures. among different types of these techniques, accumulative roll bonding (arb) has been extensively used to produce multi-layered composites. in the present study, a new manufacturing process for cu/ni- 1vol% fe3o4 composites was developed by using copper and nickel sheets toge...

In this study accumulative roll bonding (ARB) process up to 8 Cycles (equivalent strain of 6.4) at ambient temperature was used in order to improve the mechanical properties of Commercial purity titanium (CP-Ti).Several experiment has been done and Mechanical properties of specimen has been discussed. For investigating optical microscope punching and hardness test were utilized. This is the fir...

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...

In this study, Al/Al2O3 composites with two different particle sizes of 1 µm and 0.3 µm were produced via accumulative roll bonding (ARB). The microstructure evolution, mechanical properties and fracture behavior of the composites were investigated. Results show that higher ARB cycles are required to achieve a uniform distribution of particles in the composite with 0.3 µm particle size. During ...
