| Abstract Scope |
Cu-rich compositionally complex alloy (Cu-CCA) has shown the formation of Cu-rich and Fe-rich f.c.c. phases as a result of spinodal decomposition in an as-cast state. The volume fraction of the Fe-rich phase was lower and exhibited a worm-type morphology. The mechanical incompatibility between the two phases was measured via nanoindentation, and the alloy displayed classical hetero-deformation-induced (HDI) strengthening during tensile deformation. Hence, it was apparent that the morphology and distribution of the Fe-rich phase can affect the mechanical response of Cu-CCA, to study this, the alloy was first fabricated using different casting routes differing in cooling rates. Moreover, the alloy is also subjected to three cold-rolling reductions such that the level of deformation is increased, which alters the morphology and distribution of the Fe-rich phase. The quantification of this morphology and size change is done using aspect ratio and XRD analysis which is beneficial in optimizing mechanical response of Cu-CCA. |
