Abstract
AbstractMolybdenum disilicide based composites containing different types of additive materials such as SiC and nano SiC particles have been investigated, based on the detailed examination of their microstructures and fracture surfaces after creep. The materials were prepared via powder metallurgy using high temperature controlled reaction sintering (CRS). The creep experiments were carried out in four-point bending mode in air in the temperature range from 1273 to 1673 K, with constant stress of 100 MPa. The creep behaviour and the mechanisms of damage were investigated on fracture surfaces by SEM and the microstructure and its response to high temperature load were investigated by TEM using the thin foil technique.
