The grain size, and therefore the grain boundary density, is known to play a major role in the
flow stress of metallic materials. A linear relationship to the inverse of the square root of the …

The past decade was marked by significant advances in the development of severe plastic
deformation (SPD) techniques to achieve new and superior properties in various materials …

Advanced structural materials are expected to display significantly improved mechanical
properties and this may be achieved, at least in part, by refining the grain size to the …

A mechanical constitutive relationship is the basis for the design and application of structural
materials, and the establishment of a mechanical constitutive relationship generally relies on …

Billets of pure Mg were processed using two ECAP dies with internal channel angle of 90°
and 120° for 4-passes of route Bc at 225° C. Finite element analysis was used to investigate …

This study presents a comprehensive evaluation of Equal Channel Angular Pressing
(ECAP) processing on the structural evolution and mechanical properties of AA2xxx …

Magnesium and its alloys have tremendous potential as biodegradable implant materials
but finding the right compromise between corrosion resistance and mechanical properties is …

Abstract A Cu-2.5 Ti-0.4 Cr-0.1 Mg (wt%) alloy was prepared in a vacuum medium frequency
induction furnace. The evolution of the microstructure and mechanical properties of the …

Magnesium-Zinc-Zirconium (Mg-Zn-Zr) alloys have caught considerable attention in medical
applications where biodegradability is critical. The combination of their good …

Severe plastic deformation (SPD) processes are forming techniques that impose large
