| Abstract Scope |
Phase separation via spinodal decomposition is well known to produce self-ordering nanoscopic distributions of coherent phases within immiscible systems. Due to the lack of an activation barrier aside from that required for diffusion, the morphology of the compositional modulation has demonstrated a pronounced sensitivity to variations in the local energy landscape within the lattice, such as near dislocation structures. The presented study investigates the role of dislocations and other defect structures in the phase separation of Fe-25Cr-10Co. Local and bulk deformation techniques are combined with ex-situ and in-situ microscopy and nano-mechanical characterization to analyze the evolution of the spinodal structure across various temperature ranges. |
