Experimental, numerical and theoretical results describing the creep crack growth behaviour of several high temperature steels and alloys are reported. The alloys chosen cover a wide range of deformation behaviour and of crack tip controlling parameters like stress-intensity factor K, C (exp *)integral, C (ind h) (exp *)-integral, and J-integral. The results are discussed in terms of a load-parameter map.
