Investigation of the interaction between recovery and precipitation in a model austenitic alloy: Experimental and modelling results

We investigated the microstructural evolution of six austenitic alloys containing increasing amounts of Nb and C. The experiments involved the room-temperature deformation of tensile samples in the solution-treated condition, followed by annealing treatments at 700-950°C. The samples were characterized using the techniques of small-angle neutron scattering, election microscopy and yield stress measurements. We interpreted the results in terms …
