Abstract

The martensitic steel DIN1.4914 (MANET) belongs to the prospective materials developed for construction of future fusion reactors. The evolution of microstructure of this steel under tempering at 700°C has been investigated by neutron diffraction. The analysis of diffraction profile was used to determine some microstructural parameters, such as a mean microstrain, a mean size of coherently diffracting blocks and a dislocation density. These results are discussed in the context of different thermal treatments applied (cooling rate 150°C/min and 3600°C/min) and results of other techniques on the same set of samples. © 1998 Elsevier Science B.V.
