The effect of the chemical composition on the structure of Cr‐Al‐C was studied by combinatorial thin film synthesis. By changing the Cr/C ratio from 1.72 to 3.48 and the Cr/Al ratio from 1.42 to 4.18 the formation of Cr 2 AlC, Cr 2 Al and Cr 23 C 6 phases was observed. Furthermore, based on X‐ray diffraction a single phase Cr 2 AlC composition region is identified in the Cr‐Al‐C phase diagram. Throughout the studied composition range the lattice parameters of Cr 2 AlC were independent of the chemical composition.
