Unlike dislocation-driven amorphization that forms nanoscale amorphous bands (nano-ABs, &gt;5 nm thick), supra-nanometer amorphous bands (SN-ABs, &lt;5 nm thick) emerge via lattice distortion under extreme localized shear localization rather than dislocation accumulation. Concurrently, localized heating from plastic deformation triggers nanocrystallization within nano-ABs, generating randomly oriented nanograins. The amorphization and nanocrystallization are expected to provide an extra toughening mechanism for HEAs by dissipating strain energy and impeding shear localization. Crucially, we establish a microstructural link between low-temperature serrated flow behavior and thermo-mechanical instability: stress drops and strain bursts correlate with heat-induced phase transitions and nano-ABs/SN-ABs formations.</div></div>","PeriodicalId":423,"journal":{"name":"Scripta Materialia","volume":"266 ","pages":"Article 116783"},"PeriodicalIF":5.3,"publicationDate":"2025-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144130885","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By controlling the loading rate, the thermally activated behavior of dislocations and the reconstruction ability of Cottrell atmospheres were modulated. Results demonstrate that higher strain rates increase yield strength while reducing ultimate tensile strength and ductility. Microstructural analysis reveals a shift from dislocation cells to planar slip structures with rising strain rates, suggesting suppressed cross-slip.

However, these empirical equations, typically derived using linear regression algorithms, are often simplistic and may fail to capture the complex interactions among multiple alloying elements that influence the Néel temperature. Moreover, their applicability is usually limited to specific compositional ranges. In this study, we propose a CALPHAD based approach and develop a surrogate decision tree based regression model capable of capturing the interactions among multiple alloying elements to predict the Néel temperature.
