Manufacturing and Properties of a Magnesium Interpenetrating Phase Composite.

The manufacturing and properties of the AE44 magnesium alloy reinforced with SiC-Al2O3SiO2 ceramic foam were studied. The interpenetrating phase composite was manufactured by gravity casting at different preheating temperatures of the ceramic foam. The samples were investigated using optical and electron microscopy, energy dispersive X-ray spectroscopy, X-ray diffraction, transmission electron microscopy and compression testing. The interfadal reaction products (AISiRE and AIMgSiRE) between the metal phase and ceramics were influenced by the preheating temperatures of ceramic foam and reduced the compression strength significantly.
