Interfacial reaction in AZ61/AZ91/P100 Mg/graphite composite: an Auger spectroscopy investigation

The influence of isothermal treatment at 400°C on the microstructure of a magnesium alloy/graphite composite was studied. The composite was characterized by Auger electron spectroscopy, scanning electron microscopy, energy dispersive X-ray analysis and X-ray diffraction. Due to thermal treatment, the reaction zone containing carbides grows.
