Summary

Dense Mullite/Mo composites of varying compositions (0–100 vol.% of Mo) have been prepared by Pulse Electric Current Sintering (PECS) Technique. Commercially available Mullite and Mo powders have been used as the starting materials. All the composites have been sintered to near theoretical density at 1500°C in less than 5 minutes. Densification behavior of the composites with respect to Mo content has been discussed. Young's modulus, Vickers hardness, bend strength and fracture toughness have been measured for all the compositions and the results have been discussed with respect to metal content. Microstructural analyses have been carried out for the sintered and fractured specimens.
