The micropillar compression results reveal a pronounced correlation between the mechanical behavior of micropillars and various microstructural parameters, including the cementite inclination angle (CIA), interlamellar spacing, and ferrite-cementite distribution. Furthermore, strain gradient crystal plasticity finite element analysis (SG-CPFEM) revealed a significant increase in geometrically necessary dislocations (GNDs) at the ferrite-cementite interfaces, which critically influences the effective slip resistance. The simulations also indicated that the presence of a ferrite-cementite interface significantly elevates GND concentrations, impacting the load-displacement behavior. Micropillars with cementite normal to the loading direction showed higher increases in GNDs, while reduced cementite spacings were found to amplify GND formation due to increased strain gradients in the ferrite phase.

In this study, we improved the SHR of the alloys from negative to 1.5 GPa by tailoring multi-scale heterostructures, including the microscopic bimodal grain distribution, submicron spherical C14 Laves phase, nanoscale local chemical fluctuations (LCFs), and atomic clusters less than 1nm. The strength of the alloy was raised by 13.8 %, and the UTD increased by 710 % compared with the initial homogenized sample, and overall performance was superior to most LRHEAs. Bimodal grain interfaces can effectively coordinate the strain distribution between the two during deformation, accelerating the generation and storage of geometrically necessary dislocations (GNDs), and the back stress accumulates and increases with strain, stabilizing the hardening ability. Meanwhile, the meticulously dispersed C14 Laves phase plays a role in precipitation strengthening without compromising plasticity. The matrix's LCFs and Al-Zr atomic clusters can further regulate the morphology and distribution of statistically stored dislocations (SSDs). On the one hand, they could effectively pin dislocations and cause them to bend, increasing the migration resistance of SSDs; on the other hand, dislocation tangles resulting from microbands blocking and the interaction of multi-slip systems activate new dislocation sources, which lead to the rapid expansion of secondary microbands in a reticular manner. Those significantly increase the synchronous dislocation multiplication rate and dynamic dislocation density during plastic deformation, maintaining high and sustained SHR of alloys.

Compared with single-step warm-rolling (WR) treatment, the imposed cold deformation of CWR process not only results in more and finer dislocation cells in DRV grains, but also leads to texture optimization with intensity weakening and component changing. Hence, the CWR sample shows a higher yield strength (YS, ∼1.35 GPa) and ultimate tensile strength (UTS, ∼1.6 GPa) without sacrificing the tensile elongation (TEL, ∼57%) at LNT (liquid nitrogen temperature), accompanied with a significantly lower mechanical anisotropy. The exceptional cryogenic strength-ductility synergy can be attributed to following: i) the difference of YS comes from the additional Taylor hardening effect (∼150 MPa); ii) the prefer-orientated DRV grains with a high Schmid factor (SFR) of twinning induces the twin deflections or kinks at the dislocation boundary in the early deformation stage; and iii) the refined cell structure can increase the critical resolved shear stress (CRSS) of twin, act as twin nucleus and impede its growth, leading to the occurrence of high-density of nano-twin segment (thickness: ∼15 nm, number density: ∼1.1 × 10⁸ m^-3) at a high stress and strain level. Thus, the cooperative forest dislocation hardening (∼870 MPa) and dynamic Hall-Petch strengthening (∼220 MPa) effects can provide continuous strain hardening capacity.

For instance, metastability engineering that exploits phase transformation or deformation twinning depends on a minor modification in atomic compositions. Distinct from the well-studied control of elemental compositions, this work centers on a straightforward thermomechanical process of hot rolling to induce bulging of grain boundaries and core-shell dislocation cell structures. During the hot rolling, the bulging of grain boundaries releases high-density dislocation walls and more dislocations are distributed around the grain boundaries in equiatomic CoCrFeMnNi, one of the most studied high-entropy alloys. Under the tensile deformation at cryogenic temperatures with decreased stacking fault energy, the less stable grain boundaries promote the emanation of partial dislocations and the consequent formation of deformation twinning. As a result, the hot-rolled alloy exhibits an enhanced combination of yield strength of ∼941 MPa and uniform elongation of ∼54% at –196 °C, which is counterintuitive to low ductility of as-rolled metallic materials. This lies at the upper bound in comparison with tensile responses of precipitation-strengthened high-entropy alloys and high-strength steels. The higher propensity of deformation twins in hot-rolled alloy compared to that of cold-rolled and annealed one enhances strain hardening despite the hot-rolled state.
