Creep damage by pore nucleation and growth limits the lifetime of components subjected to loading at high temperature. In this work, the creep damage evolution in the aluminium matrix composite AA6061 + 22 % (Al 2 O 3 ) P  is observed in-situ by the fast-tomography technique using a miniature creep device. Reconstructions of the gauge volumes of the creep samples show particle delamination, pore formation and growth at 300 °C and additional particle fracture at 200 °C during the creep process. The results reveal that both the number of pores and the total pore volume show exponential growth with creep time, whereas the average volume of individual pores remains almost constant. The total pore volume increases linearly with the creep strain with a stress-dependent factor of proportionality.
