Magnesium alloys are of considerable current interest for use as degradable implants due to
their unique properties including biodegradability, biocompatibility, low density and …

Although several strategies (including grain refinement, texture adjustment, precipitation
hardening, etc.) have been verified to effectively improve the mechanical properties of …

Magnesium (Mg) and its alloys usually show relatively low strength and poor ductility at
room temperature due to their anisotropic hexagonal close-packed (HCP) crystal structure …

The strain rate (ε˙) and temperature (T) dependent mechanical response of single crystal
magnesium (Mg) micropillars compressed along the [2¯ 110] direction (a-axis) is …

Refractory high-entropy alloys (HEAs) usually exhibit high strength but limited ductility. Here,
we report high strength (∼ 1334 MPa) and large ductility (∼ 18.8%) in nitrogen-doped …

The aim of this work is to investigate the effect of grain size on slip activity, a critical issue for
materials design that remains unsolved. Three pure magnesium polycrystals with average …

In the early 1950's, Hall1) and Petch2) described their respective measurements made on
iron and steel materials of the polycrystalline grain diameter dependence of the yield stress …

This work investigates the origin of the simultaneous increase in strength and ductility that
takes place in Mg polycrystals alloyed with Al and Zn solutes. With that purpose, twelve …

This work presents a method to incorporate the micro Hall-Petch equation into the crystal
plasticity finite element (CPFE) framework accounting for the microstructural features to …

Abstract Models for grain size dependence of flow stress typically ignore contributions from
geometrically necessary dislocations (GNDs) in the grain boundary regions. Ashby had …
