The micro addition of Ca is demonstrated to noticeably increase the strength and ductility of
Mg–Zn–Ce alloy, which is closely correlated with the enhanced alloying segregation at grain …

Increasing the level of grain boundary (GB) segregation is one of the effective strategies for
the preparation of new high-performance Mg alloys. Here based on careful experimental …

The role of alloying element segregation at grain boundary on the microstructure and
mechanical properties is investigated in the case of Ca, Ce, and Nd addition in Mg-1Zn …

Micro-alloying of Ca in Mg–1Zn-0.3 Nd (wt.%) alloy is found to significantly improve tensile
strength and process high ductility simultaneously. It closely correlates with grain refinement …

Abstract Ca single or Ca–Ce double microalloying Mg–Zn alloy was cast and extruded in the
present study. The combined addition of Ca and Ce improved the mechanical properties of …

Grain boundary precipitation and segregation play an important role in determining
mechanical properties of Mg alloys. In the present work, we studied work focuses on the …

Abstract Effects of solute segregation at grain boundaries (GBs) on the deformation
mechanism and fracture behavior remain obscure for magnesium (Mg) alloys. Here, by …

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 …

Compared with the sole Ca or Ce/La element, the Ca-Ce/La synergistic microalloying
represents an excellent strengthening effect in extruded Mg–Zn alloy, which is mainly …

A new low-alloyed Mg-2Sm-0.8 Mn-0.6 Ca-0.5 Zn (wt.%) alloy is prepared by low-
temperature and low-speed extrusion. The as-extruded alloy has ultra-high yield strength …
