“…This type of fracture developed due to nucleation of micro-voids at the tip of the cracks, their growth and coalescence by strong shear deformation and consequently fracture took place on the shear plane [60,61]. This mechanism of fracture development has also been observed and well reported by Naseri et al [60] in hybrid composite and during ARB by the same researcher [61] in another investigation with 2024 alloy. Wang et al [62] have shown that the ductility of materials decreased after ECAP deformation and uniform elongation became very limited and subsequently, a drastic reduction of work hardening ability.…”

In this article, an effort has been made to investigate the evolution of microstructure, texture and mechanical properties of AA 7075 alloy during equal channel angular pressing (ECAP) by route B C at room temperature at a pressing speed of 1 mm/ min. Transmission electron microscopy (TEM) revealed the presence of rod-like (MgZn 2 ) precipitates in annealed conditions which were broken after two ECAP passes along with remarkable grain refinement due to high imposed strain after the second pass. After two consecutive ECAP passes, hardness, yield strength, and tensile strength of the alloy increased significantly in comparison to initial annealed condition. The fraction of high angle boundaries (HABs) and grain misorientation angle significantly increased after ECAP passes compared to the initial condition. Texture measurements were performed by X-ray diffractometer (XRD), on TD plane (parallel to extrusion direction). Texture results revealed the dominance of C and A * 2 components after the first pass and the presence of strong B , B and Ā components along with weaker A * 2 , C components after the second pass. Scanning electron microscopy (SEM) revealed that the average dimple size was gradually reduced with increasing the ECAP passes.

“…Dobatkin et al showed an increase in strength of UFG AA2024 after HPT accompanied by a decrease in grain size to the UFG regime. Goodarzy et al observed a similar behavior in ECAP processed AA2024 and Naseri et al used an advanced ARB process to increase the ductility of ARB processed AA2024 with high strength. Terada et al showed the positive effect of the ARB process on the mechanical properties of pure titanium.…”

Accumulative roll bonding (ARB) is a very useful method to produce ultrafinegrained (UFG) sheet material with extraordinary mechanical properties. Besides the production of UFG mono-materials, it is possible to create tailored multicomponent materials by stacking different materials. In this work, the aluminum alloy AA2024 and titanium grade1 are roll-bonded in order to achieve laminated metal composites (LMC) with an UFG microstructure. The mechanical properties and microstructural evolution during the ARB process of the LMC are analyzed and compared to that of LMCs. The mono-materials show an ultrafine grain structure after at least three ARB cycles which results in an increased yield and ultimate tensile strength. Most interestingly, the produced LMCs exhibit mechanical properties which are way better than the properties of the UFG mono-materials, when a linear rule of mixture is applied. The strength of the titanium-aluminum laminate is very close to the strength of the UFG titanium. Although, the density is significantly lower. The light-weight potential of the LMC is best expressed by the specific strength. Compared to the specific strength of UFG mono-material titanium of about 168 Nm g À1 and UFG monomaterial aluminum of about 195 Nm g À1 the ARB laminate exhibits the highest specific strength of about 217 Nm g À1 after three cycles.

“…It is noteworthy that few articles have also reported simultaneous improvement in strength and ductility. Naseri et al [82] proposed a new strategy for the simultaneous increase in both strength and ductility of AA2024 where after each ARB cycle, an annealed AA2024 strip is laid between the two roll-bonded strips resulting in a composite with a bimodal microstructure consisting of coarse and ultrafine elongated grain structures.…”

Different manufacturing processes can be utilized to fabricate light-weight high-strength materials for their applications in a wide spectrum of industries such as aerospace, automotive and biomedical sectors among which accumulative roll bonding (ARB) is a promising severe plastic deformation (SPD) method capable of creating ultrafine grains (UFG) in the final microstructure. The present review discusses recent advancements in the ARB process starting with the ARB basics, intricacies of the underlying mechanisms and physics, different materials, surface and rolling parameters, and finally its key effects on different properties such as strength, ductility, fatigue, toughness, superplasticity, tribology and thermal characteristics. Moreover, results of recent computational investigations have also been briefed towards the end. It is believed that ARB processing is an emerging area with tremendous opportunities in the industrial sector and ample potential in tailoring microstructures for high-performance materials.
