Lightweight structural materials are increasingly sought after in the automotive and aerospace industries for their potential to improve fuel efficiency. Magnesium-based metal-matrix composites candidates these kinds of applications. The use recycled carbon fibres offers further energy cost savings. fibre were manufactured by stir casting with high-dispersion shearing, then extruded subsequentl...

A new class of magnesium alloys has been developed by dissolving large amounts of oxygen atoms into a magnesium lattice (Mg-O alloys). The oxygen atoms are supplied by decomposing titanium dioxide nanoparticles in a magnesium melt at 720 °C; the titanium is then completely separated out from the magnesium melt after solidification. The dissolved oxygen atoms are located at the octahedral sites ...

Due to their low density, magnesium alloys are very appealing for light-weight constructions. However, the use of most common alloy, AZ91 (Mg 9 wt.% Al, 1 Zn), is limited temperatures below 150 °C due creep failure. Several with an improved resistance have been developed in past, example alloy MRI 230D or Ca-alloyed variants. there ongoing discussion literature regarding mechanisms resistance. ...
