In this study, single- and double-pass hot compression tests were performed on LX82A steel using the Gleeble-3500 thermal simulator. The dynamic and static softening behavior, as well as the evolution of microstructure, was investigated under deformation temperatures ranging from 900 to 1100 °C, a strain rate of 1 s⁻¹, and holding times varying from 1 to 120s. The results showed that the stress values in the double-pass flow curve decreased as temperature, deformation amount, and holding time increased, and the stress values were all higher than those in the single-pass flow curves. At 900 °C, the static softening mechanism was mainly static recovery. As the temperature increased, the static softening mechanism changed from static recovery to static recrystallization. The nucleation and growth mechanism of static recrystallization followed the strain-induced boundary migration (SIBM) mechanism. Compared to single-pass deformation, the double-pass deformation process was more advantageous for grain refinement. By combining static softening rate and the Avrami equation, a static recrystallization kinetics model was established, and the activation energy for static recrystallization of LX82A steel was calculated to be 218.32 kJ/mol.</p></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"60 38","pages":"17829 - 17847"},"PeriodicalIF":3.9,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145142868","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 polyurethane/water glass (PU/WG) composites offer high early strength and elasticity, their use is limited by long curing times and high costs. To overcome these limitations, this study incorporates fly ash (FA), a coal-based solid waste, into PU/WG to develop eco-friendly FA/PU/WG composites (0–20 wt% FA). Systematic investigations revealed that FA addition reduced curing time by 37% (from 122 to 77 s) through alkaline activation, concurrently facilitating the formation of a hydrated sodium aluminosilicate (N–A–S–H) gel network that enhanced interfacial crosslinking. The maximum reaction temperature initially increased (0–10 wt% FA) due to accelerated curing kinetics but decreased at higher FA contents (15–20 wt%) owing to the improved thermal conductivity of Al₂O₃ in FA combined with incomplete FA activation. Microstructural analysis (SEM/EDS) confirmed the reinforcing role of FA in microspheres; however, excessive FA incorporation (&gt; 15 wt%) led to a reduction in compressive strength, as limited Na₂O content restricted FA activation. The optimal formulation (15%-FA/PU/WG) achieved a compressive strength of 67 MPa, ultra-low permeability (1.24 × 10^–25 cm/s), and negligible heavy metal leaching. By repurposing waste FA as a functional filler, this work reduces material costs while providing a sustainable, high-performance solution for water-sealing applications, bridging industrial waste recycling with advanced engineering needs.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"60 37","pages":"16973 - 16983"},"PeriodicalIF":3.9,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145128754","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}

Studies have shown that in terms of mix proportions, an optimal magnesium oxide to phosphate (M/P) molar ratio of 4:1 to 5:1 and a water-to-cement ratio of approximately 0.16 result in better water resistance. Regarding mineral admixtures, materials such as fly ash, metakaolin, slag, steel slag, sintered sludge ash, and red mud can enhance water resistance by filling pores and participating in hydration reactions. As for chemical admixtures, waterproofing agents, retarders, and inorganic salts can improve water resistance by forming hydrophobic layers, promoting the formation of crystalline products, or filling capillary pores, respectively. In terms of curing conditions, it is crucial to avoid humid environments during the curing stage, and extending the curing period under natural conditions before immersion in water also contributes to improved water resistance.

This study explores the synergistic effects of electron beam (EB) irradiation and nano-tin (SnO₂) reinforcement in polyvinyl alcohol/polyvinylpyrrolidone (PVA/PVP) composite films, focusing on their structural modifications and functional improvements. PVA/PVP/SnO₂ nanocomposite films were fabricated via a solution-casting method and subsequently exposed to 30 kGy of EB irradiation to assess the impact of radiation-induced crosslinking and nanoparticle incorporation. A major breakthrough in this work is the significant enhancement of polymer crosslinking due to EB irradiation, resulting in a notable increase in gel fraction and structural stability—an effect that has been underexplored in this polymer system. Structural characterization using X-ray diffraction and Fourier transform infrared spectroscopy revealed considerable changes in crystallinity and molecular interactions, contributing to improved material integrity. Additionally, the introduction of 3 wt% nano-tin effectively mitigated particle agglomeration, ensuring uniform dispersion and leading to substantial improvements in mechanical properties. Tensile testing demonstrated a remarkable increase in ultimate tensile strength and elongation at break, surpassing previous benchmarks for similar polymer nanocomposites. Beyond mechanical enhancements, this study uncovers novel insights into the electronic transformations induced by EB irradiation. Optical absorption analysis revealed a decrease in the optical band gap energy and an increase in Urbach energy, indicating the formation of localized defect states that enhance charge transport. Electrical conductivity measurements further confirmed a significant increase in conductivity, highlighting a unique interplay between radiation-induced defect formation and nano-tin reinforcement—an effect not previously reported in PVA/PVP nanocomposites. These findings present a promising avenue for developing radiation-responsive polymer nanocomposites with tunable mechanical resilience, structural integrity, and electronic properties. The potential applications span across flexible electronics (e.g., advanced display technologies, wearable sensors), energy storage devices (e.g., high-performance batteries, super capacitors), and biomedical applications (e.g., radiation-sterilized biodegradable films for medical implants and drug delivery systems). Furthermore, due to their enhanced conductivity and durability, these nanocomposites hold strong potential for next-generation electromagnetic shielding materials in aerospace and telecommunications, where lightweight, radiation-resistant polymers are highly desirable.
