Herein, zinc (Zn) is introduced as a bioactive ingredient, and the difference in the physical properties of Ti and Zn elements is managed through a designed two-step spark plasma sintering process to prepare dense core–shell heterostructural Ti-Zn alloys consisting of pure Ti cores and Ti-Zn intermetallic eutectic shells. The well-bonded core–shell interfaces, the effect of dislocations and twins within the Ti cores, and the hetero-deformation-induced strengthening collectively contribute to the superior tensile and compressive properties of Ti-Zn alloys. Thus, Ti-7Zn and Ti-3Zn exhibit the highest tensile and compressive strengths of 694.4 and 2247.4 MPa, respectively. Notably, these alloys simultaneously maintain a low elastic modulus comparable to bone. As the Zn content increases, the hardness and wear resistance improve. Moreover, the wear and corrosion resistance of Ti-Zn alloys surpasses that of pure Ti, effectively mitigating tissue damage caused by debris and excessive ion release when used as implants. This study can provide insights into the fabrication of bioactive Ti-based alloys and components with significantly different melting points.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"28 6","pages":""},"PeriodicalIF":3.3,"publicationDate":"2026-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147570100","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}

Dental restorative materials, as the material cornerstone for restoring oral functions, not only influence the oral treatment effects but also lay the foundation of oral treatment technique development. This leads to extensive attention and studies of dental restorative materials, from both scientific and engineering communities. Conventional restorative materials such as metals, ceramics, and resins have been clinically used for several centuries due to their good mechanical properties and biocompatibility. Recently, a new generation of biomimetic dental restoration materials has been synthesized by mimicking the formation process or structure of natural teeth to achieve matchable properties to natural teeth. However, there are still some issues that need to be addressed for these current materials, such as insufficient properties, esthetic characteristics, or scalable fabrication, which need to be summarized and discussed. Here, we introduced the characteristics of different kinds of dental restorative materials and focused on discussing the advantages, drawbacks, structure-performance relationship, and clinical application evaluation of these materials. Additionally, we provided an outlook for the development of dental restorative materials, serving as a guideline for future material design in dental restoration.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"28 6","pages":""},"PeriodicalIF":3.3,"publicationDate":"2026-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147566263","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}

The mechanical behavior is evaluated by uniaxial tensile testing, Charpy V-notch (CVN) impact testing, and three-point bending. The thickness of each layer varies between 40% and 60% of the total thickness. The yield stress of the bilayer material follows the rule of mixtures. The fracture strain is essentially independent of the volume fraction of the soft and hard layers in the above range. For the bilayer materials, the energy absorbed during CVN tests shows a strong dependence on the volume fractions of the soft and hard layers. The results also depend on whether the notch is machined into the TWIP or CFB side. In general, the samples show an increase in energy absorption as the percent thickness of the unnotched layer increases. When the notch is positioned in the CFB layer, interface delamination leads to the arrest of the crack. As a result, the TWIP layer can experience very large deformation. When the notch is positioned in the TWIP layer, the crack propagates slowly through the TWIP steel, allowing for codeformation of both layers.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"28 6","pages":""},"PeriodicalIF":3.3,"publicationDate":"2026-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adem.202501470","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147565562","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

FeCoNiCr/MXene composite coating exhibits a face-centered cubic structure with numerous microprotrusions distributed on its surface, identified as MXene microstructures encapsulated by FeCoNiCr.

To address this issue, we investigated a lithium-based grease blended with carbon nanoparticle (CNP) additives to improve electrical conductivity and mitigate surface damage. Electrochemical impedance spectroscopy confirmed that nanoparticle inclusion significantly reduced grease impedance, enhancing its ability to conduct charge through the contact interface. Tribological analysis revealed that the presence of CNPs suppressed electrical pitting, reduced friction, and altered the dominant wear modes from electrothermal degradation to more benign adhesive wear. Notably, the pitting density decreased from 9.4% in the base grease to just 2.5% with 1 wt% CNPs, confirming the effectiveness of nanoparticles in suppressing localized electrical discharges. The grease formulation containing 0.5 wt% CNPs provided the optimal balance, minimizing surface damage while maintaining conductivity. Mechanistically, the CNPs form conductive percolation pathways within the grease, allowing current to pass through the lubricant film and thereby preventing localized discharge and thermal damage at asperity junctions. This work opens an alternative route for designing electrically functional greases that mitigate current-induced damage, extending component life in high-performance electrified environments.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"28 6","pages":""},"PeriodicalIF":3.3,"publicationDate":"2026-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adem.202502084","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147563859","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among these, recently fabricated 3D graphene structures with hollow-walled gyroid geometry, which are characterized by triply periodic minimal surfaces, demonstrate notable potential for enhanced mechanical performance and structural integrity. This study investigate the influence of hollow diameter, temperature, and strain rate on the mechanical behavior and fracture mechanisms of graphene gyroid nanostructures using molecular dynamics simulations. The results reveal critical role of the hollow diameter in modification of mechanical properties. Smaller diameters promote localized stress concentrations and early crack initiation at strut junctions, leading to lower tensile strength and stability, while larger diameters facilitate more uniform stress distribution and delay crack propagation, resulting in superior mechanical performance. Stress–strain curves exhibit serrated behavior, indicating repeated cycles of crack initiation and arrest, which enable the structure to redistribute stress and delay catastrophic failure. Additionally, mechanical properties are found to be highly sensitive to temperature and strain rate, with tensile strength decreasing at higher temperatures due to intensified atomic vibrations, and increasing at higher strain rates due to restricted defect mobility and limited structural relaxation.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"28 6","pages":""},"PeriodicalIF":3.3,"publicationDate":"2026-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147570010","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}
