Abstract Microalloying additions to Mg-Zn base alloys can refine precipitation and improve
hardening, but their effect on the microstructure at the grain boundary regions are seldom …

Precipitate microstructures in Mg-2.0 Gd-1.2 Y-0.75 Zn-0.2 Zr alloy were investigated and
the characteristic and mechanism of microstructure evolution in the alloy were discussed …

Abstract Mg–5Zn–2Gd–0.4 Zr alloy (wt.%) shows a significant age hardening response with
a hardness increment from 62 HV to 72 HV by ageing at 200° C for up to 80 h. Transmission …

A strategy is proposed to enhance the microstructure and mechanical properties of Mg–Zn
alloys by combining microalloying additions of the rare earth element Ce and the non-rare …

The microstructure, aging behavior and mechanical properties of cast Mg–3Nd–3Gd–x Zn–
0.5 Zr (x= 0, 0.5, 0.8, 1 wt%) alloys are investigated in this work. Zn–Zr particles with different …

Zirconium (Zr) is an important alloying element to Mg-Zn-based alloy system. In this paper,
we report the formation of the β-type precipitates on the nanoscale Zr-rich particles in a Mg …

To obtain thorough understandings of precipitation process in heat-treatable Mg-Ca-Zn
alloy, we revisited the precipitation process of a Mg-0.3 Ca-0.6 Zn (at.%) dilute alloy during …

The effect of pre-ageing deformation on the size and distribution of β1′ precipitates and
subsequently on the resulting strength and ductility have been measured in a Mg-3.0 at …

Precipitate phases in an Mg–7Gd–3Y–2Zn–0.5 Zr alloy aged isothermally at 240° C were
examined using high-resolution transmission electron microscopy (TEM) and high-angle …

The effect of Li additions and microalloying with Ag and Ca on the age hardening of a Mg–
2.4 Zn–0.16 Zr alloy is studied. The addition of Li up to 2at% enhances the age hardening …
