Abstract

Precipitation models such as the so called 'class-model' are capable of
reproducing complex situations such as anisothermal heat treatments
and providing the evolution of the size and volume fraction of
precipitates. They are now routinely used in particular in the field of
precipitation strengthening. To feed the model with realistic thermo-kinetic
properties of the alloy, a direct comparison with experimental
data is needed. While this can be performed relatively easily on a single
composition of an alloy, testing different compositions in multiple
conditions can become very tedious. We have used time- and space-resolved in situ small angle X-ray scattering (SAXS) on diffusion couples
prepared from pure Cu and Cu-2at%Co to study the kinetics of
precipitation for all the intermediate super-saturations. The data
obtained at different temperatures (450°C, 500°C and 550°C) provides
an extensive set of information that can then be directly compared to
class-model simulations.
