Among various crystallization methods, electro-crystallization offers distinct advantages by circumventing issues such as embrittlement, making it an effective approach for fabricating amorphous composite materials. In this study, we employed pulsed electric current processing to controllably generate nanoscale crystalline phases in a Zr53Cu18.7Ni12Al16.3 (Vit106) BMG system. Through systematic variation of current parameters, we investigated the influence of different electric pulse treatments on crystallization behavior and mechanical properties. Our results reveal that controlled current application induced temperature rises (ΔT) ranging from 1069.31 to 1464.10 K, leading to the formation of spherical crystalline clusters. This enabled successful fabrication of amorphous-nanocrystalline composites containing 5–30 % nanocrystalline fractions, with compressive plasticity reaching up to 17.2 %. Through comprehensive characterization using XRD, DSC, TEM, and SAED, we elucidated the thermodynamic behavior during electric pulse heating and the corresponding crystallization kinetics. Key findings demonstrate that electric pulse heating can achieve ultra-rapid heating rates sufficient to surpass the crystallization temperature of BMGs. Moreover, the crystallization degree and crystal size can be precisely tuned by adjusting the pulse duration, establishing this method as an efficient and controllable processing route for manufacturing amorphous-based composite materials.</div></div>","PeriodicalId":16461,"journal":{"name":"Journal of Non-crystalline Solids","volume":"672 ","pages":"Article 123840"},"PeriodicalIF":3.5,"publicationDate":"2026-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145518665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While the conventionally prepared glassy films rejuvenate through a spatially homogeneous process, the ultrastable glass films, typically produced by physical vapor deposition, transform differently: a mobility front originates at the free surface and moves inward at a roughly uniform speed. This speed depends on the material properties and the annealing temperature, and it scales approximately inversely with the <em>α</em>-relaxation time. In this work, we develop a continuum framework based on the free energy minimization, leading to a modified Allen-Cahn equation that captures both homogeneous and front-mediated relaxation dynamics. This equation is designed to represent the contrast in mobility and the associated thermodynamic driving forces, thereby linking molecular-scale relaxation behavior to mesoscopic front propagation phenomena. Although experimental evidence supports the existence of mobility fronts during the glass-to-liquid transition, the development of a predictive theoretical framework remains an open challenge. Key unresolved questions include how deposition conditions govern front velocity, the extent to which this phenomenon is universal across diverse glass-forming systems, and whether a unified model can be formulated to describe rejuvenation dynamics in a broad class of non-crystalline solid materials.</div></div>","PeriodicalId":16461,"journal":{"name":"Journal of Non-crystalline Solids","volume":"672 ","pages":"Article 123800"},"PeriodicalIF":3.5,"publicationDate":"2026-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145518663","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Laser conditioning shows pronounced potential to improve its laser damage resistance by pre-irradiated with sub-threshold laser pulses. However, it still causes the degradation in performance, and even catastrophic damage, limited by the unresolved defect evolution under laser irradiation, where contradictory mechanisms, i.e., defect reduction versus multiplication, are yet to be clarified. To clarify this issue and uncover the mechanisms and influencing factors of defect evolution, this work investigates the dynamic behavior of defects during laser conditioning using non-bridging oxygen hole center (NBOHC) as an example. The results reveal that both multiplication and reduction of NBOHC could occur on the same sample with the improvement and degradation in laser induced damage threshold, demonstrating bidirectional evolution of NBOHC. Elevated temperatures drive the transition from the reduction to multiplication, and the corresponding turning point depends on the initial NBOHC population. The competing between NBOHC multiplication and reduction is elucidated. Specifically, NBOHC multiplication arises from bond cleavage at overcoordinated Si sites, while reduction occurs via the reverse reaction, recombination with E’ center, or conversion into other defects. Finally, an evolution model is proposed to predict whether the NBOHC multiplication or reduction dominates under given condition. These findings contribute to the understanding of defect bidirectional evolution during laser conditioning and offer insights for improving the performance of fused silica.</div></div>","PeriodicalId":16461,"journal":{"name":"Journal of Non-crystalline Solids","volume":"671 ","pages":"Article 123853"},"PeriodicalIF":3.5,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145475501","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
