“…A modeling technique for predicting the incremental increase in strength due to ARB processing by relating the process parameters and number of ARB cycles to the mechanical properties (i.e., ultimate tensile strength) has recently been proposed by Milner et al [37]. This modeling technique has (i) the initial strength of the material and (ii) the number of ARB cycles (which is also equivalent to the accumulative strain) as major inputs.…”

“…To estimate the flow stress at large strains, Hughes et al [41,46] derived a strength structural relationship that is the sum of the contributions from dislocation strengthening and boundary strengthening (grain refinement). The grain refinement during ARB, and probably CARB processing, may be associated with a mechanism of grain fragmentation due to the generation of highangle grain boundaries that subdivide the parent crystal [37,[47][48][49][50]. The deformation-induced high-angle boundaries are formed by incidental dislocation boundaries (IDBs) and geometrically necessary boundaries (GNBs) [51].…”

“…Their model accurately predicted the grain refinement and hardness of an ARBed alloy. Milner et al [154] simulated the evolution of material strength of an ARB-processed titanium alloy that was then validated using experimental data exhibiting an acceptable fit in whole range of ARB cycles. To further validate the model for a wider range of materials, five different materials were also investigated and the results confirmed the ability of the proposed method in predicting the strengthening behavior of all the considered materials.…”

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.

“…Pukanszky proposed that the interfacial interaction between the polymer matrix and filler plays a key role in improving the tensile strength of polymer composites . In other words, the major reason for the enhanced tensile strength of composites is because of the stress transfer from filler to the polymer matrix through the interphase region, which creates a greater interfacial interaction.…”

Nanocomposites based on neodymium-doped titanium dioxide (Nd-TiO 2 )/poly(n-butyl methacrylate) (PBMA) have been prepared by an in situ polymerization of butyl methacrylate monomer with varying concentrations of Nd-TiO 2 nanoparticles. The resulting nanocomposites have been analyzed by ultraviolet (UV)-Visible spectroscopy, Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscope (SEM), differential scanning calorimetry (DSC), thermogravimetric analysis, and impedance analyzer (TGA). The results of UV and FTIR spectroscopy have indicated the interaction of nanoparticles with the PBMA matrix. Spherically shaped nanoparticles with an average size of 10-25 nm have been revealed in the TEM and their homogeneous dispersion, and interaction of polymer matrix has been confirmed by SEM and XRD studies. The thermal stability and glass transition temperature of the composites were significantly enhanced by the addition of nanoparticles. The AC conductivity and dielectric properties of nanocomposites have been found to be higher than pure PBMA, and the maximum electrical properties have been observed for 7 wt% composite. The reinforcing nature of the nanoparticles in PBMA has been reflected in the improvement in tensile strength measurements. The result indicated that the tensile strength of nanocomposites have greatly enhanced by the addition of Nd-TiO 2 nanoparticles whereas the elongation at break decreases with the loading of nanofillers. To understand the mechanism of reinforcement, tensile strength values have been correlated with various theoretical modeling. The research has been found to be promising in the development of novel materials with enhanced tensile strength, dielectric constant, and thermal properties, which may find potential applications in energy storage and nanoelectronic devices.
