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...

A severe plastic deformation process, termed accumulative extrusion bonding (AEB), is conceived to steady-state bond metals in the form of multilayered tubes. It shown that AEB can facilitate their solid-state, like process roll (ARB). The steps involve iterative extrusion, cutting, expanding, restacking, and annealing. As iterated, laminated structure layer thicknesses decrease within tube wal...

Differential Scanning Calorimetry (DSC) is a thermal analysis technique that measures the energy absorbed or released by a sample as a function of temperature or time. Analysis by DSC has wide applications for examining solid-state reactions and solid-liquid reactions in many different materials. Quantitative analyses of the kinetics of reactions may be assessed by reviewing the interrelation b...

In recent years, the fabrication of bulk materials with ultra fine grain sized materials processed by SPD methods. Different techniques have been used to introduce large plastic strains in to bulk metals such as Equal Channel Angular Pressing (ECAP) [1-3], Accumulative Roll Bonding (ARB) [4-7], Repetitive Corrugation and Straitening (RCS) [8,9], Constrained Groove Pressing (CGP) [5] and Constra...

The work carried out by the authors over the last decade on the processing, microstructural characterization and the mechanical behaviour of Mg alloys is reviewed. In particular, the potential for grain refinement and for the development of specific textures of large strain hot rolling (LSHR), equal channel angular pressing (ECAP) and accumulative roll bonding (ARB) is discussed. The recrystall...

Ultrafine grained sheets were prepared from a twin-roll cast AA8006 aluminium alloy using accumulative roll-bonding process at room temperature. The evolution of microstructure of sheets after three accumulative roll-bonding passes during isochronal annealing with a constant step of 20 °C/20 min was studied by light and electron microscopy. The influence of the resulting microstructure on mecha...

An ultra low carbon interstitial free (IF) steel was severely deformed by the six-layer stack accumulative roll-bonding (ARB) process for improvement of the mechanical properties. As-received material with 1mm in thickness showed a recrystallization structure with average grain diameter of 27mm. The ARB was conducted at ambient temperature after deforming the as-received material to 0.5mm thick...

Lead composites have been used as anodes in the electrowinning process to produce metals such copper and zinc. Manufacturing stable lead with appropriate mechanical chemical properties is required improve performance of process. In this study, an accumulative roll bonding (ARB) method was fabricate a Co/Pb nanocomposite. Utilizing ARB can help us achieve uniform structure enhanced via severe pl...

The current study adopted a quantitative approach to investigating the mechanical properties, and their relationship to the microstructural features, of precipitation-strengthened 6061 aluminum alloy processed through accumulative roll bonding (ARB) and aging heat treatment.  To serve this purpose, the contributions of different strengthening mechanisms including grain refinement, precipitation...
