Before the MAX phases can be used as high temperature structural materials their resistance to creep and oxidation need to be well understood. Of all the MAX phases, the most resistant to oxidation are Ti2AlC, Ti3AlC2 and Cr2AlC. A literature review shows that some claim that the oxidation kinetics to be parabolic, others cubic. At this time, there is little doubt that the oxidation kinetics are cubic. The tensile and compressive creep results of Ti3SiC2 and Ti2AlC, with varying grain sizes in the 1000–1200 °C temperature range, suggest that ripplocations and grain boundary sliding are the dominant creep mechanisms. A comparison of the creep properties of Ti3SiC2 with other high temperature materials suggests that it can be used at higher temperatures but only if the applied stresses are low.
