Randomized trial investigates microstructure regulation and mechanical properties of 2195 Al-Li alloy, indicating enhanced performance.

The aim is to design a multi-directional forging process that regulates microstructure and enhances mechanical properties of 2195 Al-Li alloy.
Proposed variable-temperature multi-directional forging process
Investigated microstructural evolution and enhancement mechanisms
Analyzed mechanical properties such as ultimate tensile strength and yield strength.
VTF-10U9S process achieves average grain size of 23.5 μm with significant grain refinement
Ultimate tensile strength (UTS) reached 583.1 MPa and yield strength (YS) reached 542.3 MPa due to synergistic strengthening mechanisms
Average elongation of 7.3% attributed to fine-grained structures and secondary phase dispersion, reducing anisotropy.

Zheng et al. (2026) studied this question.
