Abstract
In the secondary regime of the tensile creep of Ti2AlC, made with commercial powders with a grain size of 14 +/- 8 mu m, the minimum creep rate is given by a power law, with a stress exponent of 2.5 +/- 0.3 and an activation energy of 362 +/- 83 kJ mol(-1). Dislocation creep-with possibly grain boundary sliding-are presumed to be the dominant creep mechanism(s). The high failure strains (>15%) can be partially attributed to substantial grain kinking near the fracture surface and concomitant damage tolerance. (C) 2012 Acta Materialia Inc.
