Composite material comprising a magnesium alloy and method of preparation thereof

A particulate composite comprising, based on the weight of the composite:

• from about 86 to about 94 weight percent (wt. %) of a magnesium (Mg) alloy;
• from about 3 to about 7 wt. % of titanium (Ti);
• and,
• from about 3 to about 7 wt. % of multiwalled carbon nanotubes (MWCNT),
• wherein the Mg alloy includes, based on the weight of the alloy:
• from about 5.5 to about 6.5 wt. % of aluminium (Al);
• from about 0.1 to about 0.5 wt. % of manganese (Mn);
• from about 0.1 to about 1.0 wt. % of the combination of zinc (Zn) with at least one element selected from the group consisting of copper (Cu), iron (Fe), nickel (Ni), and silicon (Si);
• and,
• a balance consisting of Mg and inevitable impurities,
• wherein the particulate composite has:
• a median volume particle size (Dv50) of from about 10 to about 35 micrometers (μm), as determined by Scanning Electron Microscopy;
• and,
• a surface area of from about 1 to about 60 meter square per gram (m2/g), as determined by Brunauer-Emmet-Teller (BET) analysis.
