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 …

Ultrafine-grained and heterostructured materials are currently of high interest due to their
superior mechanical and functional properties. Severe plastic deformation (SPD) is one of …

The present study unraveled the defining role of small silicon (Si) addition (5 atomic%) in
dramatically altering the plasticity mechanisms, grain refinement and hardening response of …

Age-hardened 6201 aluminum alloy wires utilized in high-voltage transmission lines need to
have high strength, high conductivity and high ductility. However, simultaneously obtaining …

Strengthening by grain refinement via the Hall–Petch mechanism and softening by
nanograin formation via the inverse Hall–Petch mechanism have been the subject of …

In this paper, the deformation mechanism and microstructure evolution of TiB whisker
(TiBw)/TA15 composites during high temperature (HT) rolling and tensile were investigated …

In this study, the microstructure and properties evolution of Cu-2.7 Ti-0.2 Fe alloy (wt.%)
during cold drawing and subsequent aging treatment were investigated. The grain …
