Abstract12 vol%WCp/2024Al composite was fabricated from mixed powders by hot-pressing at various temperatures. Investigation of the interfacial reaction between the WC phase and the Al alloy matrix was performed by X-ray diffraction (XRD), transmission electron microscope (TEM) and energy dispersive spectroscopy (EDS). A multiple layer interface structure, which is composed of Al/WAl12/Al4C3/WC, is found to form by the interfacial reaction during hot-pressing. Further study shows that the Al4C3 layer forms along with a given crystal orientation of WC phase and might retard the interfacial reaction process.

Investigation of the interfacial reaction between the WC phase and the Al alloy matrix was performed by X-ray diffraction (XRD), transmission electron microscope (TEM) and energy dispersive spectroscopy (EDS). A multiple layer interface structure, which is composed of Al/WAl_(12)/Al_4C_3/WC, is found to form by the interfacial reaction during hot-pressing. Further study shows that the Al_4C_3 layer forms along with a given crystal orientation of WC phase and might retard the interfacial reaction process.
