The reactive sintering of Ti/Al 4 C 3 /C mixtures at a temperature of 1417°±5°C to form the ternary carbide Ti 3 AlC 2 was studied in situ by neutron powder diffraction. A series of intermediate phases occur during the synthesis process beginning with the formation of β‐Ti, TiC x ( x ≤1) and Ti 3 AlC. This is followed by the transition of Ti 3 AlC to Ti 2 AlC, after which the Ti 2 AlC and TiC x react with each other to form the product phase Ti 3 AlC 2 .
