Figure 6. Schematic illustration of prediction for the mechanical performances from composition/processing, or the inverse design of the composition/processing for Al alloys with desired mechanical performances, based on the thermo-kinetic synergistic effects of phase transition and deformation bridged by the microstructure in terms of the defects interactions with respect to the classical strengthening/toughening modes (including the solid solution hardening, the dislocation hardening, the phase/grain boundary hardening, and the precipitation hardening modes), the quantitative correlations between strength (σ) and ductility (ε) along with thermodynamic driving force (ΔG) and kinetic energy barrier (Q), as denoted in the reaction coordinate diagram with respect to the initial state (IS), the transition state (TS) and the final state (FS) of alloy system during phase transition and/or deformation, respectively.
