However, comprehensive studies on their compositional design and temperature-dependent irradiation behavior remain limited. In this study, irradiation-induced hardening and microstructural evolution of VTiTa and VTiTaHf alloys were systematically investigated under ion irradiation at room temperature (RT) and 773 K using nanoindentation and atom probe tomography. In the VTiTa alloy, RT irradiation led to the formation of V-enriched particles and dislocations, whose number density and size were closely correlated with local compositional variations. At 773 K, these V-enriched particles disappeared, the dislocation density decreased, and their average size increased. The addition of Hf further suppressed the formation of V-enriched particles and dislocations under RT irradiation. Moreover, an atomic-scale homogeneous elemental distribution was maintained in the VTiTaHf alloy at 773 K. These microstructural changes were consistent with the observed irradiation-induced hardening behavior, where the VTiTaHf alloy demonstrated superior radiation resistance at elevated temperatures. These findings suggest that Hf incorporation not only enhances the irradiation tolerance of the alloy at high temperatures but also contributes to reducing the radioactive decay period, which is a critical requirement for application in nuclear environments.","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"126 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145203996","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}

In the context of advanced Fe-based alloys, key questions remain: What drives nanoparticle precipitation? How are core-shell structures formed? And what mechanisms underlie cooperative hardening? By introducing Al into Fe-Cu-Ni alloys, we demonstrate that Ni and Al co-cluster with Cu, forming BCC Cu(Ni,Al)-rich clusters that evolve into the thermally stable B2 phase, even after 100 h of annealing. Prolonged annealing leads to Cu diffusion into the precipitate core, resulting in a core-shell structure—a Cu-rich core surrounded by a B2-Ni(Al) shell—which correlates with a reduction in hardness. In contrast, FeCuNi alloys exhibit rapid precipitate nucleation due to the high diffusivity of Cu and Ni in the Fe matrix, but their core-shell structures show limited thermal and mechanical stability. The Cu(Ni,Al)-B2 precipitates, with their enhanced phase stability, achieve a higher number density and superior performance compared to FeCuNi alloys. Importantly, our findings reveal a strong correlation between the morphological evolution of precipitates with annealing time and their mechanical behavior, providing new insights into the design of high-performance structural materials.","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"115 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145195369","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}

However, their brittleness makes it difficult to manufacture engineering components with complex geometries. Additive manufacturing via direct energy deposition (DED) technique offers flexibility in design and forming, yet processing defects caused by marked differences in the physical properties of the constituent multi-principal elements and the rapid solidification conditions associated with DED limit RHEAs' practical application. This study elucidates the formation of inherent defects, strategies for their suppression, and their influence on the mechanical response of a DED Ti₄₁V₂₇Hf₁₃Nb₁₃Mo₆ RHEA prepared by mixed powders. Correlation of the molten pool characteristics to processing parameters reveals that laser power and scanning speed are pivotal in regulating defect formation. Insufficient energy input induces unmelted defects, rendering as-printed specimens brittle during tensile tests. Detailed microstructural characterization shows that the unmelted defects act as crack nucleation sites (through micropore coalescence), promoting premature failure. To address this, remelting (Strategy Ⅰ) and high-energy density processing (Strategy Ⅱ) were implemented via temperature field simulations and proved to be effective. The damage mechanism of the RHEA with moderate defects fabricated via Strategy Ⅰ is primarily governed by cracking, whereas that of the low-defect-content RHEA produced via Strategy Ⅱ is dominated by void nucleation. In the latter, reduced cracking effectively suppresses strain localization during deformation. The optimized RHEA exhibits a high tensile elongation of 17.9% and a yield strength exceeding 1 GPa. These findings offer a framework to design ductile DED RHEAs by tailoring processing parameters to avoid defect-induced brittleness.","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"78 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145188936","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}

Specifically, aging promoted the precipitation of <em>M</em>₂₃C₆ carbides and <em>M</em>₂(C, N) carbonitrides. <em>M</em>₂₃C₆ carbides were distributed along grain boundaries (GBs) and interdendritic regions (IDRs), while <em>M</em>₂(C, N) carbonitrides were found only in IDRs. At GBs, <em>M</em>₂₃C₆ carbides coarsened, following the Lifshitz-Slyozov-Wagner (LSW) model. At aging 5000 h, their average size reached 402.1 nm. Moreover, their number density peaked at 1.6 μm⁻² at aging 1000 h. In the IDRs, <em>M</em>₂₃C₆ carbides showed multipoint nucleation with limited growth, whereas <em>M</em>₂(C, N) carbonitrides exhibited fewer nucleation with slow growth. At aging 5000 h, the number density and average size of <em>M</em>₂₃C₆ carbides were 15 μm⁻² and 47.0 nm, respectively, while those of <em>M</em>₂(C, N) carbonitrides were 6.0 μm⁻² and 162.5 nm, respectively. Both the plasticity and the toughness of the WM deteriorated with increasing aging time, but a more rapid decline occurred when cracks were initiated simultaneously at GBs and in IDRs. During tensile loading, cracks primarily initiated at GBs and gradually intensified with aging. At aging 3000 h, additional IDR cracks formed due to precipitate accumulation in IDRs, together with the marked reduction in the number of deformation twins and microbands, jointly contributed to a faster drop in elongation from 33.0% to 27.2% between 1000 and 3000 h. In contrast, impact cracks mainly originated in the IDRs, where crack severity also increased over time. At aging 5000 h, further GBs cracking induced by coarsened and continuously distributed <em>M</em>₂₃C₆ carbides at GBs, together with the disappearance of deformation twins near the impact fracture surface, jointly contributed to a faster drop in impact toughness from 164.0 J to 141.5 J between 3000 and 5000 h.","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"67 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2025-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145183319","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}

We employed material extrusion (MEX) AM to prepare an ultrafine-grained WC-0.5Cr₃C₂-0.2CeO₂-9Co cemented carbide.

Specifically, SiC whiskers with high-density SFs were catalytically grown using an Fe-mediated liquid-solid interface during polyborosilazane pyrolysis. These SFs serve as effective polarization centers, significantly enhancing dielectric loss capability. By optimizing Fe content, fewer crystalline phases and high SFs density were achieved in SiBCN, thereby realizing impedance matching and strong dielectric loss. Consequently, the unique microstructure expanded the effective absorption bandwidth of SiBCN from 4.82 to 6.36 GHz at 2.1 mm thickness, demonstrating record-breaking broadband absorption performance among PDCs.

The joints exhibited an ultimate tensile strength of 91–97 MPa, with fracture surfaces characterized by dimpled zones and fractured brittle intermetallic compounds (IMCs) grains, revealing a ductile-brittle mixed fracture mode strongly correlated with Sn grain orientation. The formation of subgrains and mechanical twins during tensile indicated that the plastic deformation was governed by the concurrent activation of dislocation slip and twinning. Subgrains formation originated from dislocations slipping along the dominant {100}&lt;001&gt;, {110}&lt;001&gt;, and {101}&lt;111&gt;/2 slip systems, as well as the rotation of Sn lattices constrained by the solder/Cu interfaces. Meanwhile, mechanical twins occurred via atomic deformation along the [−101] direction in the {101}&lt;101&gt; twin system. Specifically, one out of four atoms displayed along the slip direction, while the other three atoms rearranged to occupy new lattice positions, with subsequent crystal layers shifting to support mechanical twins formation. In general, under tensile conditions, geometrically necessary dislocations initially generated near grain boundaries, progressively accumulated at subgrain boundaries, and stored within grains, ultimately activated twinning to form mechanical twins upon subsequent dislocation blockage. And the results pointed out that Sn grain with small |∆<em>λ</em>| preferred to form subgrains by slip, while Sn grain with large |∆<em>λ</em>| would generate twin grains by twinning during tensile.
