Processing science for nanocrystalline metals has largely focused on far-from-equilibrium
methods that can generate many grain boundaries with excess defect energy. Conversely …

The effects of high-pressure torsion (HPT) processing on an Al–Mg–Si alloy (AA6060) have
been investigated comprehensively. We show that the processing temperature has complex …

This review focuses on grain growth behaviors and the underlying mechanisms of bulk
electrodeposited nanocrystalline nickel and nickel-iron alloys. Effects of some important …

Abstract In this work, Mg/Al bi-layered disks were fabricated by high pressure torsion (HPT)
at room temperature. A 0.26 µm layer of γ-Mg 17 Al 12 intermetallic formed at the interface of …

The grain size of polycrystalline materials plays a major role in dictating many critical
properties including the strength and resistance to plastic flow. Nano/ultra-fine grained …

Peculiar effects of the grain sizes of nanostructured materials based on metals (Ni, Fe, Cu,
Co, Ti, Zn, Zr, and Mg), alloys (Fe-Cr, Ni-Cr, Ni-Cu, Ni-Ti, etc.), and refractory compounds …

Severe plastic deformation has been used widely to refine the grain structure and enhance
the strength of magnesium alloys. However, the processing of these materials by Equal …

Atom probe is a technique that is highly suited to the study of nanocrystalline materials. It
can provide accurate atomic-scale information about the composition of grain boundaries in …

The microstructural evolution and mechanical properties of ultrafine grained interstitial free
steel fabricated by multipass differential speed rolling (DSR) technique were investigated. A …
