Part printability using laser powder bed fusion (LPBF) was assessed by measuring the segregation, flowability, rheology, and spreadability of the powder. Blend quality was assessed chemically and visually via computed tomography and scanning electron microscopy. Carbon blends above 0.25 wt% C produced significant segregation of carbon particles. Agglomerated carbon segregates acted as barriers to flow causing the reduction in dynamic flow by 40–60% compared to the virgin powders. High carbon contents also limited powder spreadability by promoting large streaks during powder spreading. Below 0.25 wt% C, the deleterious effects of segregation, flowability, and spreadability were reduced and the powder characteristics were comparable to the processable virgin powders. Printed parts exhibited very small effect of carbon blending on the density and micro-hardness of the material. The grade 23 powder is more suitable for carbon blending and offers the highest part densities and lowest variation in material hardness. This is attributed to lesser carbon agglomeration, better powder flow, and fewer interstitial elements.</div></div>","PeriodicalId":383,"journal":{"name":"Materials & Design","volume":"253 ","pages":"Article 113833"},"PeriodicalIF":7.6,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143684510","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, HAl66-6–3-2 alloy was subjected to EPT, and the results revealed that the EPT sample achieved an increase in plasticity without compromising the strength, with an elongation rate enhancement of 69.89 %. The changes in performance are mainly attributed to three aspects: grain refinement, slight decrease in dislocation density, and the formation of strong {632}<223> texture during the EPT. Unlike the untreated (UT) samples with entangled dislocations, under the coupling effect of Joule heating and non-thermal effect, the dislocations in EPT samples exhibited directionality, primarily composed of a series of parallel dislocation pairs. The formation of the strong {632}<223> texture primarily relied on grain boundary migration and grain rotation, with both Joule heating and non-thermal effect facilitating rapid grain boundary migration. At low-angle grain boundaries, the pulsed current facilitated grain rotation, transforming low-angle grain boundaries in the <em>β</em> phase into high-angle grain boundaries. The study demonstrates EPT can promote the movement of atoms and regulate the microstructure, which is of great significance for the subsequent control of alloy properties.</div></div>","PeriodicalId":383,"journal":{"name":"Materials & Design","volume":"253 ","pages":"Article 113836"},"PeriodicalIF":7.6,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143684514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this issue, we developed a Prussian blue nanohybrid hydrogel by pre-coupling of polymer materials and inorganic nanomaterials <em>via</em> covalent bond, improving the stability of the organic–inorganic interface as well as nanozymes within the nanohybrid hydrogel. The nanohybrid hydrogel retained the enzymatic activities of Prussian blue nanoparticles, and its enzymatic activities displayed temperature-dependent characteristics when in proximity to physiological temperature. In light of this, we combined graphene-based far-infrared photothermal therapy with nanohybrid hydrogel materials, in order to promote wound healing by thermal effects and improved enzymatic activity. Animal experiments demonstrated that this combination significantly accelerates diabetes wound healing, alleviating wound inflammatory responses, and promote collagen deposition and neovascularization.

This study presents a groundbreaking method that, for the first time in published literature, leverages in-situ Ni alloying with a flexible laser-arc hybrid heat source to create an exceptionally high-performing nanoscale double solid solution interface between immiscible Mg and Fe alloys. This processing approach enables the high metallurgical reaction temperatures required for immiscible and nonreactive systems. The resulting lattice formation, driven by localized elemental diffusion at elevated interfacial temperatures, fosters adaptive coherent matching across the entire Mg-Fe interface. This process successfully transforms the non-coherent lattice that is generally observed at the Mg/Fe interface into a coherent double solid solution interface with the bulk matrix on both sides, significantly enhancing bonding efficiency and performance.

The sensor employs electrospinning and electrostatic spraying techniques to prepare a liquid metal-polyimide matrix material, with polyvinyl alcohol modification significantly enhancing its adhesion. Notably, an ultrasonic impregnation method was utilized to uniformly disperse conductive fillers onto the surfaces of the nanofibers and within the three-dimensional skeletal structure, creating a dual-conductive network that enhances the sensor’s conductivity. The sensor exhibits high sensitivity (3.02 kPa<sup>−1</sup>), rapid response/recovery times (80 ms/200 ms), and a broad detection range (0–90 kPa), along with excellent mechanical stability and durability (5000 loading–unloading cycles). These advantages enable the flexible pressure sensor to detect various signals from minor body movements to larger motions, such as throat swallowing and finger bending.

Calibrated through numerous additively manufactured samples, a high-fidelity mathematical model, grounded in Helmholtz resonance principles and the Transfer Matrix Method, was developed to accurately predict the acoustic properties of plate lattices across a broad range of frequencies from 450 to 6300 Hz. The model not only effectively predicts sound absorption coefficient curves based on geometric parameters but also provides valuable insights into how these parameters influence acoustic performance. It is found that smaller cell sizes, higher relative densities, and reduced perforation sizes generally result in higher mean sound absorption coefficients. The frequency bands of peak absorption regions are then strongly affected by the perforation size relative to the cell size. Furthermore, an optimization framework leveraging the model generated heterogeneous plate lattice designs with superior broadband sound absorption at targeted frequency ranges.
