The main aim of the research programme was to gather and
create adequate information needed in the assessment of
the structural integrity of the reactor pressure vessels
made of the steels concerned. Special emphasis was on the
microstructural characteristics and basic mechanical
properties evaluation as a function of varying heat
treatments. An additional objective was to generate
technical data for pressure vessel manufacturing,
especially heat treating.
As a result of the programme recommendations for
austenitizing and tempering treatments could be given.
The microstructure after a wide variety of heat
treatments proved to be granular bainite.
