2019, Journal of Alloys and CompoundsCitation Excerpt :Recent studies have focused on how to improve its strength and ductility, and it is well documented that the strength of magnesium alloys are directly related to grain size [6]. A reduction in grain size can enhance the ductility of magnesium alloys without sacrificing their strength [7,8], so various potential grain refiners were employed on casting Mg-Al based alloys such as carbon inoculation [9–12], adding alloying elements [13–17] and adding particles etc. The most commonly accepted theory for carbon inoculation on the grain refinement is that Al4C3 act as heterogeneous nuclei for the α-Mg phase during solidification [11].
An analysis of the factors affecting strengthening in carbon fiber reinforced magnesium composites
2019, Composite StructuresCitation Excerpt :Similar to the matrix part in Fig. 7(a), there are precipitates about 100 nm uniformly dispersed in the matrix of the PyC-Cf/AZ31 composite (Fig. 10). It is generally accepted that the fine and uniform precipitates are benefit to the mechanical property of Mg-Al alloys due to the dispersion strengthening [48,56–58]. According to the rule of mixture, the enhancing of the matrix would contribute to the strengthening of composite.
Effect of Al content on microstructure and mechanical properties of as-cast Mg-5Nd alloys
2018, Journal of Alloys and CompoundsCitation Excerpt :With the addition of Al ranging from 1.6 wt% to 3.0 wt%, the location of polygonal Al2Nd phase and acicular Al11Nd3 phase is associated with phase formation reaction during solidification. According to the existed Al-Mg-Nd ternary phase diagram [23,24] and the report of Zhang et al. [25], it is considered that the Al2Nd phase might be directly formed from the liquid phase prior to the formation of α-Mg phase. It is most likely that the peritectic reaction of L + Al2Nd → α-Mg occurs as the temperature reduces.
