Fabrication of Al/Ni/Cu composite by accumulative roll bonding and electroplating processes and investigation of its microstructure and mechanical properties

Fabrication of Al/Al2O3/TiC hybrid composite by anodizing and accumulative roll bonding processes and investigation of its microstructure and mechanical properties

“…3, by increasing the number of ARB cycles, the distribution of reinforcement particles in aluminum matrix became more uniform whereas after the eighth cycle, no deboning and porosities were observed between the aluminum layers and at the interface of matrix and particles. Similar results were reported by other authors in different systems [17,18].…”

“…These phenomena improve the ductility of composite. The results are in good agreement with the results obtained by other researches [15][16][17][18].…”

“…However Jamaati and Toroghinejad [17] have succeeded to produce Al/Al 2 O 3 composite by anodizing and ARB processes instead of commonly-used alumina powder. The resulting composite demonstrated that the porous nature and uniform thickness of alumina layers produced by anodizing process helped creating an improved bonding between the aluminum layers and uniform distributed [18] applied ARB and electroplating processes to fabricate Al/Ni/Cu composite. In which, Nickel was electroplated on copper substrate.…”

Deformation textures of aluminum in a multilayered Ti/Al/Nb composite severely deformed by accumulative roll bonding

“…Furthermore, since the mating materials have dissimilar properties, the laminated composite tends form a more heterogeneous structure, where, most of the effective reduction was accommodate by the softest phase [32], leading the Al layers were still viable to provide enough work-hardening ability during the primary ARB cycles. However, when the number of ARB cycles increased, such inhomogeneous deformation in layer refinement was constrained due to forming a uniform distribution of redundant shear [33], thus, the individual Al layer promptly achieved to its working hardening limit owing to the elevating dislocation density [34,35]. Also, Since the Al in this tertiary system has the highest stacking faculty energy in comparison with Ti and Nb,, thus, it is expected the Al layers gained the least strain hardening rate along with increasing of ARB cycles, thus, the least rate gaining in hardness when processed by consecutive ARB cycles.…”

Microstructure and properties of BN/Ni-Cu composites fabricated by powder technology

“…Metals as Al, Mg, Fe, Ti, Ni, Cu, Ag, Co and Nb or alloys as Ni-Cu, Zn-Co, Co-Ni, Ni-Fe were mainly used as metallic matrices [2]. Among others nickel as a durable and tough metal has been widely used, due to it's resistant to corrosion and abrasion [3]. There are several techniques for the fabrication of MMCs.…”
