Strategies to improve the cryogenic toughness generally involve stabilizing a face-centered cubic (<em>fcc</em>) phase to prevent this transition; however, this involves alloying with high concentrations of nickel, cobalt, and chromium, which are expensive and unsustainable due to their high environmental impact, energy-intensive extraction processes, and limited global reserves. Here, we engineered a low-carbon, micro-alloyed steel to possess a dual-phase, ultrafine-grained ferrite/martensite lamellar microstructure. This structure confers an unusual inverse-temperature dependence of impact toughness across a broad temperature range (383 K to 77 K) and exceptional resistance to fracture under both impact and quasi-static loading conditions at cryogenic temperatures (77 K). These properties are achieved through a combination of extrinsic toughening from delamination and crack bridging, as well as intrinsic toughening by interface dislocation-mediated plastic deformation within ferrite and activation of multiscale substructure sliding in martensite. This microstructural design strategy offers a pathway to engineer plain <em>bcc</em> steels with exceptional cryogenic damage tolerance without the addition of expensive and critical elements.</div></div>","PeriodicalId":387,"journal":{"name":"Materials Today","volume":"95 ","pages":"Article 103279"},"PeriodicalIF":22.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147388259","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A persistent debate surrounds how dislocation cellular structures strengthen materials. This study, utilizing in-situ tensile straining transmission electron microscopy, unveils the presence of two distinct types of cell walls, differentiated by the presence or absence of discernible crystallographic misorientations across the cell walls. Cell walls with misorientations act as dislocation sinks and absorb dislocations, whereas cell walls without misorientation hamper dislocation motion by forest dislocation entanglement. These contrasting cell wall–dislocation interaction mechanisms lead to different structural stabilities of cell walls. Cell walls with misorientations tend to maintain their structural integrity during deformation, while cell walls without misorientation are prone to dissolution under high strain. These deformation behaviors suggest that the dislocation cellular structure enforces both dislocation hardening and boundary hardening mechanisms, contingent on the type of dislocation cell walls. This study further demonstrates that by varying additive manufacturing parameters, the fractions of different types of cell walls can be adjusted, thereby enhancing the overall mechanical properties.</div></div>","PeriodicalId":387,"journal":{"name":"Materials Today","volume":"95 ","pages":"Article 103268"},"PeriodicalIF":22.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147388274","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we present a new synthesis route to fabricate ultra-strong, highly plastic, and thermally stable HEAs-TF leveraging the unique capabilities of pulsed laser deposition (PLD). We demonstrate our approach by focusing on CoCrCuFeNi, a model FCC HEA of the original Cantor family. Specifically, we synthetize ultrafine grain structures with controllable size (down to 12 nm) which can be further tailored by post-thermal annealing treatments, resulting in high hardness (11 GPa) and yield strength (2.0 GPa) due to Hall-Petch strengthening, outperforming similar HEAs-TF while maintaining high plasticity (no fracture at 30% strain). Moreover, these ultrafine HEAs-TF shows enhanced thermal stability, grain growth starting at <em>T</em> = 49% of <em>T_m</em> (melting temperature), while maintaining high hardness (9.1 GPa) after annealing for 1 h at 460°C.

However, the commercialization of LFMP is hindered by its intrinsically low electronic conductivity, one-dimensional tortuous Li⁺ diffusion channels, and Mn-induced Jahn-Teller distortions. These factors, compounded by lattice strain during Fe²⁺/Fe³⁺ and Mn²⁺/Mn³⁺ redox transitions, lead to anisotropic stress, Li⁺ transport barriers, increased internal resistance, and rapid capacity fade. This review systematically examines the structural and electrochemical behavior of LFMP across compositions, morphologies, and doping strategies. We analyze operando phase evolution, defect chemistry, and Li⁺ migration pathways to elucidate the mechanistic origin of electrochemical fading. Particular emphasis is placed on solid solution stabilization, anti-site defect engineering, and elastic strain modulation via ion substitution and particle miniaturization. We synthesize insights across compositional design (multi-metal doping, Fe/Mn ordering), crystallographic defect control (e.g., anti-site Li⁺/M²⁺ engineering), and morphological strategies (strain-accommodated nanoarchitectures), outlining approaches to extend solid-solution regimes and mitigate mechanical degradation.

Controlled thermomechanical cycling introduces well-recovered low-angle dislocation boundaries that progressively reconstruct straight solidification grain boundaries into a tortuous network rich in large-dihedral-angle triple junctions. Experiments and finite-element modeling reveal that this reconstruction is driven by cyclic high-temperature plasticity beneath the melt pool. Large-scale molecular dynamics simulations show that these large-angle triple junctions act as potent crack arrestors, promoting crack-tip blunting and dislocation-mediated plasticity.
