“…In a binary Al-Sc system, the precipitation kinetics were studied by earlier works [6][7][8]. Any possibility of clustering before precipitate formation has been ruled out by the previous works [9].…”

“…As a promising and attractive age-hardened aluminum alloy, Al-Sc alloy has been extensively investigated in experimental and numerical studies [1][2][3][4]. In binary Al-Sc alloys, Sc additions provide an excellent improvement in mechanical properties owing to the formation of a highnumber density of nano-scale L1 2 -Al 3 Sc precipitates during aging [5][6][7][8].…”

Abstract. A micromechanical phase-eld model is utilized to study the evolution of nanostructure Al3Sc phase in Al-Sc alloy. We study the formation of Al3Sc precipitates in an Al-Sc alloy by using an elastic phase-eld model. Since the precipitates of Al 3 Sc phase are fully coherent with the Al matrix, the elastic energy will have an in uence on the resulting morphology. We have studied the e ects of elastic strain energies on shape evolution of Al 3 Sc phase, numerically. The simulated nano-structures evolve from spherical to cubic shapes. The equilibrium shape of the coherent Al3Sc phase is found to be determined by minimizing the sum of the elastic and interfacial energies through the phase-eld equations. A coherency loss is observed when the precipitates reach a speci c size. The simulation results show good agreements with previous experimental studies.

“…Thus, in clarifying the mechanical properties and microstructural characteristics of Al-Sc alloy, it is necessary to investigate the deformation behaviour over a full range of strain rate and temperature conditions. The literature contains many investigations into the beneficial effects of adding Sc to Al alloys, including its age hardening effects [6][7][8] grain refinement properties [9,10], superplasticity effects [11][12][13][14], and weldability characteristics [15,16]. However, the high strain rate deformation behaviour of Al-Sc alloy over a full range of operating temperatures has attracted relatively little attention.…”
