A relationship between the microstructure and multiaxial creep properties of PM2000 tubes is discussed. The microstructure was investigated by X-ray diffraction, optical metallography, scanning- and transmission electron microscopy (TEM). Creep properties were established at 1000 degrees centigrade under multiaxial loading. The results show a low creep ductility and intergranular failure of tubes at high temperatures, related to the microstructural and mechanical anisotropy. The development of a special pancake grain structure is seen as a factor for increasing the life time of tubes subjected to multiaxial creep.
