“…The strength and elastic modulus of magnesium alloys are low. The properties of magnesium alloys can be significantly enhanced via the addition of particles, fibers, nanofibers, and nanotubes to form metal matrix composites (MMC) [ 5 , 6 , 7 , 8 , 9 , 10 ]. The Young’s modulus of magnesium alloys can be increased via the particles, whiskers, and fibers.…”

Composite materials based on magnesium–lithium (MgLi) and magnesium–yttrium (MgY) matrices reinforced with unidirectional carbon fibers were prepared using the gas pressure infiltration method. Two types of carbon fibers were used, high-strength PAN-based T300 fibers and high-modulus pitch-based Granoc fibers. The PAN-based carbon fibers have an internal turbostratic structure composed of crystallites. The pitch-based carbon fibers have a longitudinally aligned graphite crystal structure. The internal carbon fiber structure is crucial in the context of the interfacial reaction with the alloying element. There are various mechanisms of bonding to carbon fibers in the case of magnesium–lithium and magnesium–yttrium alloys. This paper presents the use of the DMA method for the characterization of the role of alloying elements in the quality of interfacial bonding and the influence on the complex modulus at increasingly elevated temperatures (50–250 °C). The complex modulus values of the composites with T300 fibers were in the range of 118–136 GPa. The complex modulus values of the composites with Granoc fibers were in the range of 198–236 GPa. The damping capacity of magnesium-based unidirectionally aligned carbon fiber composites is related to the quality of the interfacial bonding.

In the silicothermic process, some metal oxide impurities that coexist with dolomite are inevitably reduced to metal vapors which condense to metal impurities in the magnesium crystallizer. In this paper, molecular dynamics simulations were carried out to investigate the effect of impurity clusters on crystallization transition of undercooled magnesium vapor. The results showed that saturated vapor atoms tend to nucleate on the pre-existing impurity cluster, which promoted the crystallization rate of magnesium vapor. Moreover, the promoting effect depends on the species and size of impurity clusters, in the three impurities studied in this paper, magnesium vapor condenses on the Fe cluster at the fastest rate due to the bcc structure and the strong interaction between Fe and Mg atoms. The Ni cluster has a more significant promoting effect on crystallization for the Ni and Cu clusters with the same fcc structure because of a larger energy parameter.
