TY - CONF A1 - Rockenhäuser, Christian A1 - Schriever, Sina A1 - Piesker, Benjamin A1 - Skrotzki, Birgit T1 - Microstructural characterisation of ageing and creep of 2618A N2 - The degradation process of alloy 2618A was investigated and results especially regarding volume fractions are presented. An ageing model for the alloy is tentatively formulated. However, the presence of dislocations remains questionable.

The results are discussed with regard to additional microstructural characterisation of the primyra Phase and creep experiments of alloy 2618A. Different methods to determine the volume fractions of precipitate phases are presented.

Especially the formation of different precipitates (T1 and Theta') were characterized and the microstructural changes under different ageing conditions (with and without external strain) were investigated to determine the effect od stress on the ageing process.
