In this study, the morphology and size of MnS inclusions were refined by introducing nano-ZrO2 particles into the molten steel. As the ZrO2 content increased, the number of Al2O3–MnS inclusions decreased, while ZrO2–MnS inclusions became predominant core-shell inclusions. Simultaneously, MnS inclusions transformed from elongated shapes to fine spherical particles with an average area of 0.963 μm2 and a sphericity of 0.805 at a ZrO2 content of 0.0126 wt.%. Although both Al2O3 and ZrO2 acted as heterogeneous nucleation sites for MnS, first-principles calculations revealed that ZrO2 exhibited stronger nucleation capability, with the adsorption ability showing a clear gradient: monoclinic ZrO2 exhibiting the strongest adsorption, followed by tetragonal ZrO2, and finally α-Al2O3. Based on the experimental observations and theoretical results, a mechanism for ZrO2-facilitated heterogeneous nucleation of MnS was proposed. These findings provide valuable theoretical insights and technical guidance for spheroidization of MnS inclusions during steelmaking process.","PeriodicalId":501120,"journal":{"name":"Journal of Materials Research and Technology","volume":"39 1","pages":"9061-9069"},"PeriodicalIF":0.0,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147885729","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Copper nanoparticles have emerged as a promising alternative to their cost-effectiveness, superior durability, and electrical conductivity comparable to silver. However, the practical application of copper is hindered by its susceptibility to oxidation, which prevents low-temperature sintering in ambient air. This study introduces an innovative in situ preparation method for copper paste, where benzimidazole-coated copper particles are synthesized directly through a one-step process. This novel approach simultaneously integrates copper particle synthesis, in-situ benzimidazole coating, and paste formulation, thereby obtain oxidation-resistant and well-dispersed copper paste. The entire process is simple, efficient, environmentally friendly, and achieves a yield of up to 99 %. An encapsulation sintering method is further developed to protect the joint from oxidation during sintering via an epoxy sealing layer. The copper paste was successfully sintered in air at 220 °C, and exhibited remarkable performance, with a shear strength of 60.35 MPa and a low resistivity of 19.25 × 10 −8 Ω m. The method of this study effectively reduces the requirement for protective sintering atmospheres of copper nanoparticles, representing a substantial advancement for the power semiconductor industry.","PeriodicalId":501120,"journal":{"name":"Journal of Materials Research and Technology","volume":"39 1","pages":"9330-9341"},"PeriodicalIF":0.0,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147892667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, weak interfacial adhesion between short carbon fibers (SCFs) and the epoxy matrix (EP) significantly limits stress transfer and load-bearing efficiency, resulting in suboptimal mechanical performance. In this work, a synergistic interface structure (absorption-transfer interface) has been generated by combining a cut carbon nanotube (CCNTs) and self-polymerized dopamine (PDA) to efficiently absorb and transfer external loads as well as enhance electromagnetic waves loss. The incorporation of CCNTs-PDA into the silane-modified SCFs-EP (SCFs-Si-EP) results in remarkable enhancements in flexural strengths, which increase by 208%, compared with those of SCFs-Si-EP. The dominant failure mechanism changes from fiber pull-out to delamination failure after introduction of the CCNTs-PDA interface. Moreover, the SCFs-Si-EP composites exhibit an EMI shielding effectiveness of 47.3 dB with incorporation of CCNTs and 2 wt% PDA (SCFs-CP-EP-2). This enhancement is attributed to the conductive networks and scattering centers provided by the CCNTs-PDA interface layer, which facilitates interfacial polarization and optimizes impedance matching, thereby leading to efficient electromagnetic wave attenuation. As a result, the SCFs-CP-EP-2 shows excellent mechanical properties and admirable electromagnetic shielding performance.","PeriodicalId":501120,"journal":{"name":"Journal of Materials Research and Technology","volume":"39 1","pages":"6381-6394"},"PeriodicalIF":0.0,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147893278","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, Zn- x Mn ( x =0.2, 0.4, 0.6, 0.8, 1 wt.%) alloys were prepared by stir casting method, and their microstructure, mechanical properties and in vitro degradation properties were characterized and studied in detail. The results showed that the addition of Mn refined the grain size and significantly improved the mechanical properties of the alloy. Compared with the as-cast pure zinc, the hardness, ultimate tensile strength (UTS) and compressive yield strength (CYS) of Zn-1Mn alloy increased by 9.24 times, 5.02 times and 3.63 times, respectively. Meanwhile, the addition of Mn resulted in the formation of hard MnZn 13 phase in the alloy, which improved the wear resistance of the zinc alloy. In vitro degradation tests showed that the degradation rate of the alloy increased as the Mn addition increased, which was attributed to the formation of MnZn 13 phase, and the MnZn 13 phase promoted the galvanic corrosion of the alloy matrix. After two months of immersion, the UTS, elongation and CYS of Zn-1Mn alloy were 142.91 MPa, 2.06% and 148.62 MPa, respectively.

In this study, Cu-Gr nanocomposites were prepared by using pulse co-electrodeposition (PCED). An optimized microstructure comprising a high density of nanotwins and homogeneously dispersed graphene was obtained at a graphene concentration ( C Gr ) of 0.1 g/L and a pulse current density of 300 mA/cm 2 .

The Young's modulus of the Cu-Gr samples increases with increasing C Gr , with a maximum of ∼143 GPa for C Gr of 0.3 g/L, owing to the integration of graphene. The ntCu-Gr sample with C Gr of 0.1 g/L exhibits the highest hardness of ∼2.73 GPa, resulting from the synergistic strengthening effects of the nanotwins and graphene.

Phenyl silicone rubber exhibits extraordinary thermal stability, radiation resistance and weather resistance, making it particularly suitable for use in the aviation and aerospace. However, its inherent flexibility and weak intermolecular interactions result in narrow damping temperature ranges and instability of the mechanical properties at extreme temperatures, which severely limits its practical application. In this study, we designed and synthesized five soluble diphenyl MQ resins with different M/Q ratios, and developed a novel dissolution blending method to incorporate resins as damping fillers into phenyl silicone rubber to prepare high-performance damping composites. The dissolution blending method enhances interface effect and facilitates more bound rubber between phenyl silicone rubber and diphenyl MQ resin, which promotes efficient stress transfer and energy dissipation. The results show that, when the M/Q ratio is 0.8, the dissolution blended damping composite (DBDC) possesses a significant improvement of 230.9 % in the effective damping (tan δ > 0.3) temperature range compared to the blank phenyl silicone rubber. Remarkably, the DBDC also exhibits exceptional mechanical performance and aging resistance, displaying tensile strengths above 5 MPa at both 150 °C and −50 °C, maintaining over 95 % of its original tensile strength and hardness after 96h aging at 150 °C. This work proposes a viable strategy for the preparation of high-performance damping composites suitable for extreme environments.","PeriodicalId":501120,"journal":{"name":"Journal of Materials Research and Technology","volume":"39 1","pages":"3520-3530"},"PeriodicalIF":0.0,"publicationDate":"2025-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147333773","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
