AlC. Rietveld analysis of powder X-ray diffraction patterns was used to calculate the lattice parameters and phase fractions. Heating Ti, V, Al and C elemental powders-in the molar ratio of 1.5:1.5:1.3:2-to 1, 450 • C for 2 h in flowing argon, resulted in a predominantly phase pure sample of (Ti 0.5 , V 0.5 ) 3 AlC 2 . The other compositions were not as phase pure and further work on optimizing the processing parameters needs to be carried out if phase purity is desired.
