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 unique combination of very large strains, high temperatures and high strain rates
inherent to friction stir welding (FSW) and friction stir processing (FSP) and their dependency …

Lithium, the lightest and most electronegative metallic element, has long been considered
the ultimate choice as a battery anode for mobile, as well as in some stationary applications …

High strength–ductility synergy is difficult to achieve in Mg alloys. Although high strength has
been achieved through considerable alloying addition and low-temperature extrusion, these …

Grain refinement could effectively enhance yield strength of Mg alloys according to the well-
known Hall-Petch theory. For decades, many studies have been devoted to the factors …

Increasing demand of lightweight structures with exceptional properties elicits materials
processing and manufacturing technologies to tailor blanks in order to achieve or enhance …

Developing ultra-high strength in rare-earth-free Mg alloys using conventional extrusion
process is a great challenge. What is even more difficult is to achieve such a goal at a lower …

Grain growth directly influences the plasticity and strength of Mg alloys. As the grain size
decreases from the microscale to the nanoscale, the plasticity of Mg alloys continually …

A Hall-Petch slope (k) that is highly changeable with texture, as extensively reported in Mg
alloys, is ultimately related to the variation of deformation modes. In this paper, the influence …

Abstract Samples of Mg-3Gd (wt.%) were prepared by accumulative roll-bonding followed by
annealing at different temperatures to produce samples with average grain sizes ranging …
