Investigating the effects of heat treatments on nanoprecipitation of CuCrZr alloy using SANS

The aim of the ex-situ SANS experiment is to track the evolution of the size and volume percent of the Cr-rich nanoprecipitates during ageing of a CuCrZr alloy at 425℃, 450℃, 475℃ and 500℃ respectively. The chemical composition of the CuCrZr alloy will be used in the current investigation was Cu-1Cr-0.1Zr (all in wt.%). 32 samples will be prepared for ex-situ SANS measurements including samples isothermally aged at 425℃, 450℃, 475℃ and 500℃ for 10mins, 30mins, 60mins, 1h, 2h, 3h, 5h and 10h respectively. This will enable the study of the kinetics of nucleation, growth and coarsening of precipitates during the thermal aging of the CuCrZr alloy.
