However, the pursuit of achieving broadband absorption through meticulously designed polarization behavior continues to pose a formidable challenge. In this work, we present a unique multi-polarization strategy in the La(OH)₃/N-doped rGO composites, incorporating dipole polarization induced by nitrogen doping and intrinsic defects, homogeneous interfacial polarization contributed by locally crystalized nano-domains in La(OH)₃, and heterogeneous interfacial polarization at the heterojunctions between La(OH)₃ and N-doped rGO, to significantly enhance the multi-band polarization loss. Experimental and theoretical investigations reveal that the La(OH)₃/N-doped rGO hybrid featuring distinctive crystalline/amorphous nano-domains exhibits remarkable coupling effects, encompassing an enhanced electron transport rate and strengthened interfacial electron interactions. The improved electron transport is attributed to increased electron transitions at heterojunctions with matched Fermi levels and enhanced charge conduction from the crystalline regions within La(OH)₃. Furthermore, strong polarization relaxation at these heterojunction interfaces, along with weaker but significant polarization at numerous homogeneous interfaces, contributes to the enhanced interactions. Consequently, an exceptional minimal reflection loss of -69.6 dB has been achieved, accompanied by an impressive effective absorption bandwidth of 7.7 GHz, which surpasses that of the current state-of-the-art microwave absorbers. This work unveils an innovative design paradigm aimed at the meticulous regulation of polarization loss, thereby laying a robust foundation for the advancement of high-performance absorbers.</div></div>","PeriodicalId":238,"journal":{"name":"Acta Materialia","volume":"294 ","pages":"Article 121154"},"PeriodicalIF":8.3,"publicationDate":"2025-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144083246","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}

Rough diamond anvils (rough-DA) are introduced to intensify all occurring processes during heterogeneous compression of Zr in a diamond anvil cell (DAC). The main rule is found that during α-ω PT the crystallite size and dislocation density in ω-Zr depend solely on the volume fraction of ω-Zr and are independent of pressure, plastic strain tensor, its path, and initial nanostructure. Crystallite size in ω-Zr increases from 10 to 60 nm during the PT, while dislocation density reduces from 1.83 × 10¹⁵/m² to 0.6 × 10¹⁵/m². Rough-DA produce a steady nanostructure in α-Zr before PT with smaller crystallite size and larger dislocation density than smooth-DA, leading to a reduction of the minimum pressure for α-ω PT to a record value 0.67 GPa, 9 times smaller than under hydrostatic loading and 5.1 times lower than the phase equilibrium pressure. In addition to strain, the kinetics of strain-induced PT unexpectedly depends on time. Also, strain-controlled part of kinetics is zero order, in contrast to the first-order kinetics with smooth-DA. The obtained results open a new window for understanding the mutual effects of nanostructure evolution and PT during severe plastic flow in various technological and natural processes. They may bring up economic strategies of producing nanocomposites and single-phase nanostructured materials with optimal properties.","PeriodicalId":238,"journal":{"name":"Acta Materialia","volume":"7 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2025-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144083217","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}

It exceeds the electrostrain performance of neighboring compositions unilaterally displaying relaxor→MPB transition or pure glassy behavior when taking both electrostrain amplitude and thermal stability into consideration. Phase field simulation indicates that the combination of enhanced electrostrain and excellent thermal stability is ascribed to the embedding the nano-scaled glassy ferroelectric state within the MPB region of the relaxor→MPB composition, a feature enabled through introducing local fields by Ta-doping process. The optimal coexistence of micro and nano domain patterns in designed glassy ferroelectric crossover smears the microstructural difference between relaxor and MPB ferroelectric regions.

Through a series of in-situ experiments, we investigated the local variations in the evolution of microstructures and thermomechanical behaviors within a keyhole mode melt pool.

Various laser parameters were tested to assess their influences on the residual strains in the melt pools. The results revealed that the residual strain in the keyhole mode melt pool is relatively insensitive to variations in the parameters and is smaller than that in the melt pool created under conduction mode laser scanning.

They postulated that the deformation rate is governed by the flow of atoms along the direction of applied stress via a vacancy-atom exchange mechanism under diffusional creep conditions. These theories render a compelling picture for materials scientists to design microstructures with improved creep resistance. However, they remain vigorously debated due to a dearth of direct experimental evidence and poor predictions of the observed creep rates in certain materials and conditions. In this paper, we tested the hypothesis that, in alloys undergoing diffusional creep, elemental redistribution would manifest at nearby grain boundaries if the diffusivities of the alloying elements were significantly different. Furthermore, the extent of elemental redistribution would vary depending on the orientation of the grain boundary with respect to the tensile loading axis. To this end, 304L stainless steel alloy tensile specimens were crept under relatively low applied stresses (2.5-15 MPa) at 750°C. Chemical composition at the grain boundaries in the deformed and undeformed sections of the specimen were then compared and the trends were rationalized using thermodynamic and kinetic modeling. In support of our hypothesis, the results revealed a notable change in the nature and extent of creep-induced elemental redistribution (CIER). Our experimental observations of CIER, complemented with modeling results, suggested the occurrence of Newtonian diffusional creep. Further mechanistic understanding of diffusional creep via characterization and modeling of CIER is expected to make the approach more viable and enable new pathways for designing advanced creep-resistant materials for extreme environments.</div></div>","PeriodicalId":238,"journal":{"name":"Acta Materialia","volume":"294 ","pages":"Article 121137"},"PeriodicalIF":8.3,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143940140","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}

The paper shows that such interactions are crucial for the Ag(Ni) system, which is the focus of this study. We derive the Gibbs free energy for a spectral model of grain boundary segregation that properly captures solute–solute interactions strong enough to violate the random mixing assumption. Strong attractive interactions have been shown to be independent of solute concentration and can be directly incorporated into the segregation spectrum. Moreover, at zero temperature, all types of solute–solute interactions can be incorporated into the segregation spectrum, allowing the calculation of zero-temperature stability scores with regard to solute–solute interactions. This may enhance the reliability of screening for stable nanocrystalline alloys.
