The processing of bulk metals through the application of severe plastic deformation (SPD) provides the potential for achieving exceptional grain refinement leading to ultrafine-grained (UFG) materials. These materials generally exhibit high strength but very limited ductility at room temperature. The recent development in the nanoindentation technique provides significant feasibility in evaluating the micro-mechanical behavior of UFG materials. Accordingly, this review examines the available experimental results showing the enhancement in strength and ductility through nanoindentation analysis in various materials after different SPD techniques. A comprehensive tabulation is also presented listing the available data for the strain rate sensitivity, m, in a variety of UFG metals processed by SPD.

“…In literature, different SPD methods like high pressure torsion (HPT), equal channel angular pressing (ECAP), or accumulative roll bonding (ARB) were described and widely used to create UFG materials. Thereby, ARB is one of the most effective SPD method to produce large amounts of materials . Several materials like aluminum, titanium, copper, or steel have been successfully subjected to the ARB process achieving promising mechanical properties.…”

Superior Mechanical Properties of Aluminum–Titanium Laminates in Terms of Local Hardness and Strength

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.

“…To fully visualize the significant improvement of the m value on the HPT‐synthesized MMNC in the hybrid Al–Cu system, it is reasonable to compare the estimated m values for this system with the available data for various UFG Al and UFG Cu samples processed by different SPD techniques. Figure shows the variation of m value with grain size for UFG Al, UFG Cu, and for the HPT‐synthesized hybrid Al–Cu system. The encircling ovals provide a simple visualization of the general trends for the UFG Al and Cu and for the hybrid Al–Cu system.…”

Synthesis of Hybrid Nanocrystalline Alloys by Mechanical Bonding through High‐Pressure Torsion

et al. 2020

View full text Add to dashboard Cite

An overview of the mechanical bonding of dissimilar bulk engineering metals through high‐pressure torsion (HPT) processing at room temperature is described in this Review. A recently developed procedure of mechanical bonding involves the application of conventional HPT processing to alternately stacked two or more disks of dissimilar metals. A macroscale microstructural evolution involves the concept of making tribomaterials and, for some dissimilar metal combinations, microscale microstructural changes demonstrate the synthesis of metal matrix nanocomposites (MMNCs) through the nucleation of nanoscale intermetallic compounds within the nanostructured metal matrix. Further straining by HPT during mechanical bonding provides an opportunity to introduce limited amorphous phases and a bulk metastable state. The mechanically bonded nanostructured hybrid alloys exhibit an exceptionally high specific strength and an enhanced plasticity. These experimental findings suggest a potential for using mechanical bonding for simply and expeditiously fabricating a wide range of new alloy systems by HPT processing.
