Currently, existence of nanoscale spinodal decomposition (SD) phase in matrix was found to have significant impact on the properties of HEAs. Nevertheless, the morphology evolution and the kinetics of SD is not clear, which hinders in-depth understanding of the structure–property relationship. In this study, we examine the spinodal structures in (FeCoCrNi)85(AlCu)15 HEAs at different states using in-situ small-angle neutron scattering (SANS), in conjunction with transmission electron microscopy technique. The result demonstrates that SD occurred when aging the HEA samples at temperatures ranging from 500 to 800 °C, which leads to the phase constitution of NiAlCu-rich and FeCoCr-rich spinodal phases, L12 ordered phases, and FCC matrix. The characteristic wavelength of SD (({lambda }_{text{SD}})) grows from 5.31 to 51.26 nm when aging temperature rises from 500 to 800 °C, which explains the enhancement of the alloy’s microhardness.

During isothermal treatment at 700 °C, the ({lambda }_{text{SD}}) increases from 10.42 to 17.43 nm with prolonged time, and SD is in the late stage from the exponential trend of the ({lambda }_{text{SD}}) over time.

In this work, AlCoCrFeNi2.1 alloy is taken as the research object. The mechanical behaviors and deformation mechanisms of the FCC and B2 single crystals with different orientations and the FCC/B2 composites with K-S orientation relationship during nanoindentation processes are systematically studied by molecular dynamics simulations. The results show that the mechanical behaviors of FCC single crystals are significantly orientation-dependent, meanwhile, the indentation force of [110] single crystal is the lowest at the elastic–plastic transition point, and that for [100] single crystal is the lowest in plastic deformation stage. Compared with FCC, the stress for B2 single crystals at the elastic–plastic transition point is higher. However, more deformation systems such as stacking faults, twins and dislocation loops are activated in FCC single crystal during the plastic deformation process, resulting in higher indentation force. For composites, the flow stress increases with the increase of B2 phase thickness during the initial stage of deformation. When indenter penetrates heterogeneous interface, the significantly increased deformation system in FCC phase leads to a significant increase in indentation force. The mechanical behaviors and deformation mechanisms depend on the component single crystal. When the thickness of the component layer is less than 15 nm, the heterogeneous interfaces fail to prevent the dislocation slip and improve the indentation force.

The results indicate that CeO2 can be reduced by Mg to elemental Ce, predominantly in the form of the Mg-Zn-Ce phase. The addition of CeO2 notably refines the grain size of as-cast ZK60 Mg alloy, with the Mg-Zn-Ce phase primarily distributed along grain boundaries. After extrusion, grain size increases and then decreases with increasing CeO2 content, while the dynamic recrystallization (DRX) fraction gradually reduces. This behavior is chiefly attributed to the hindrance of the DRX process by a high density of second phases and the restriction of recrystallized grains growth by fine particles. The basal texture intensity increases progressively with the addition of CeO2. As the CeO2 content rises, the yield strength (YS) and elongation (EL) of the alloys show significant improvement. The increase in YS is mainly due to the combined effects of grain refinement strengthening and dispersion strengthening. In contrast, the enhanced EL is closely related to the heterogeneous structure of the grains.
