In Situ Synchrotron Radiation Diffraction Study of Compression of AZ91 Composites Reinforced with Recycled Carbon Fibres

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 subsequently heat treated. compressive deformation mechanisms compared AZ91 investigated using situ synchrotron radiation diffraction. An increase ultimate strength was achieved AZ91. active similar those Magnesium alloys compression typically show extensive twinning; this observed composites. stress required twinning onset increased composites, twin volume fraction at failure decreased
