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 …

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 …

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 …

Magnesium (Mg) alloys, as the lightest metal engineering materials, have broad application
prospects. However, the strength and ductility of traditional Mg alloys are still relativity low …

In this paper, deformation behaviors and microstructure evolution of a hot-rolled AZ31B
magnesium alloy under cyclic loadings are investigated. The relationship between plastic …

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 …

Poor formability at room temperature is a key problem that limits the application of Mg alloys.
Formability is closely dependent on both large work-hardening capacity and high tensile …

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 …

Here we reported a heterogeneous fiberous structured Mg-5.6 Zn-0.6 Zr (wt%) alloy
obtained by conventional extrusion method, which exhibited high yield strength of∼ 345 …

The current work explored additive friction stir deposition of AZ31B magnesium alloy with the
aid of MELD® technology. AZ31B magnesium bar stock was fed through a hollow friction stir …
