This work particularly focuses on spall strength, precipitation behavior and damage evolution in 2024Al alloy under ramp wave loading. The results reveal that ramp loading mitigates thermal softening through gradual stress variation and reduces dislocation–atomic interactions due to its extended rise time. Compared with square wave loading, the continuous strain under ramp loading promotes vacancy generation, facilitating abnormal precipitation. These factors collectively contribute to enhanced spall strength. The spallation mechanism is dominated by dislocation–grain boundary interactions, with void nucleation and growth primarily occurring at grain boundaries. The formation of double spall surfaces is attributed to tensile stress concentrations generated by shock wave reflections at the initial spall surface.

Guided by an Integrated Computational Materials Engineering (ICME) approach that combines Calculation of Phase Diagram (CALPHAD) and Density Functional Theory (DFT), Ta addition is screened for sluggish diffusion to effectively restricts κ-lath thickening, leading to the formation of a nanoscale semi-coherent lamellar structure. The resulting ultrahigh strength originates from the substantial strengthening effect of the nanolamellar structure, coupled with synergistic contributions from grain size strengthening and resistance stress from the matrix. Furthermore, the formation of coherent nanoscale L1<sub>2</sub> precipitates during elevated temperature deformation compensates for the strength loss observed at 923 K. The remarkable strain hardening behavior arises from the interaction between κ laths and dislocations, i.e., initial dislocation pile-ups at the κ laths enhancing the hardening rates, while subsequent dislocation shearing and stacking faults (SFs) activation in the κ laths relieving stress concentrations, synergistically stabilizing plastic deformation. Additionally, deformation-induced dislocation substructures, including 9R phases, nanotwins, and dislocation tangles, contribute to the high level of strain hardening between 77 K and 723 K.

Phase field (PF) and other continuum methods for modeling deformation twinning often incorporates self-stress effects arising from boundary defects. These self-stress fields, which are singular or discontinuous, introduce artificial forces that distort interface behavior, leading to inaccuracies in predicting interface migration and microstructure evolution. To address this issue, we propose a stress correction scheme that diminishes self-stress effects on the migration of twin interfaces. By analyzing stress field characteristics associated with three-dimensional twins with sharp or diffuse interfaces using dislocation theory and crystal plastic finite element (CPFE) method, we introduce a “correction zone” to redefine the driving force. This approach interpolates stress outside the corrected region to provide an approximate representation of the interface driving force. Validation within the CPFE framework confirms that the scheme effectively diminishes self-stress influences.
