This work studies the sintering behavior of ultrafine powder of Cr2AlC compound during nonisothermal heating using a dilatometer. Sample exhibits relatively slower densification under pressureless condition where relative density increased from about 61% (green compact) to about 73% during heating up to 1350 degrees C. Axial shrinkage data were analyzed through the volume diffusion and grain boundary diffusion-based sintering models. Estimated activation energy of sintering (352 kJ/mol) for volume diffusion mechanism, was found to be closely matching with the reported activation energy of chromium diffusivity, indicating volume diffusion as a controlling mechanism and chromium as a major diffuser in Cr2AlC.
