αʹ spinodal decomposition. Representative TEM micrograph αʹ spinodal decomposition occurring for long high-temperature exposure duration in VLE4 sample head: (a), with indexed SAEDP (inset); a detail of dislocation strengthening by ε-Cu rich nanoparticles is shown in (b), the semi-coherency of a large fraction of such ε particles is reported in (c).
