Investigations of the creep behaviour of Alloy 800H, which was heat treated under production conditions, have shown marked differences for samples from an identical batch of material. Simulating possible variations in the commercial heat treatment under laboratory conditions have indicated that the creep properties are rather sensitive to the cooling procedure. The differences can be explained by a variation in the dislocation carbide particle microstructure which results from different cooling rates after solution annealing.
