The evolution of the chemical and phase composition of carbide precipitates in X20CrMoV12.1 steel after longterm service of 56 000 θ (470 – 530 °C at up to 18MPa) and after heat treatment (650 and 800 °C) was investigated using transmission electron microscopy and Auger electron spectroscopy. The precipitates found were mostly of M type, the S- and v-phase and traces of M C. In service loaded state the presence of M precipitates was also established. The evolution sequence is obviously M C → M !M
