Nanoindentation creep behaviour and microstructural evolution of long-term crept HR3C austenitic steel

The nanoindentation creep behaviour of crept HR3C austenitic steels was investigated to study the microstructural evolution of the steel after long-term creep at 650 °C. The corresponding microstructure evolution was characterised by optical microscopy, scanning electron microscopy, electron back-scattered diffraction and transmission electron microscopy. Results show that the nanoindentation hardness and creep displacement decreased with...
