Co-design of grain heterogeneity and precipitate hierarchy for strength-ductility-conductivity synergy in a conductive Cu alloy
In this work, a coupled multiscale microstructural design strategy was developed for a Cu-5Ni-0.7Si-0.4Al alloy by integrating partial recrystallization-induced grain heterogeneity with hierarchical precipitation. Partial recrystallization produced heterogeneous grains spanning the micrometer to submicrometer scale, wh...
