The MAX phases are a class of nano-laminate materials with a unique combination of ceramic and metallic properties. Experimental investigation of the properties of the MAX phases is limited by diculties associated with producing phase pure samples. In this work the authors use first principles density functional theory calculations to examine the elastic properties of the Tin+1AlXn (X=N,C) series as a function of n with the aim of identifying optimum compositions that combine good machinability with high stiffness.
