Hydrothermal oxidation of bulk Ti 3 AlC 2 in continuous water flow was studied at 500°–700°C under a hydrostatic pressure of 35 MPa. During hydrothermal oxidation, titanium and aluminum were oxidized and selectively removed from Ti 3 AlC 2 with the survival of carbon. Reaction kinetics obeyed a linear time‐law. The hydrothermal oxidation rates were sluggish at 500– 600°C and faster at 700°C accompanied with the formation of cracks in oxides. This study clarified that the resistance of bulk Ti 3 AlC 2 against hydrothermal oxidation was high up to 700°C.
