However, the relationship between the microporous structure of sintered nanosilver materials and their macroscopic mechanical properties has not been fully explored. In this study, load–displacement curves of porous sintered nanosilver materials were obtained through indentation experiments. Finite element simulation was then applied to sintered nanosilver materials with different porosities to understand the impact of porosity on their mechanical properties. Using a two-dimensional axisymmetric indentation model based on the finite element method, sintered nanosilver with a porosity of 10% was indented to a depth of 10 <span>(upmu)</span>m. The sintered nanosilver matrix model had dimensions of 0.25 mm × 0.25 mm. Simulations were carried out on sintered nanosilver with porosities of 10, 20, 25, and 30%. Indentation curves and stress–strain curves were obtained for each porosity. The mechanical properties of the materials, such as Young’s modulus and yield strength, were analyzed using indentation curves. The results show that the Young’s modulus and yield strength gradually decrease with increasing porosity of the sintered nanosilver material. This study has successfully explained the correlation between the elastoplastic mechanical properties and the indentation response of sintered nanosilver materials with different porosities. In addition, this paper discusses the relationship between the mechanical properties and porous structure of sintered nanosilver materials in detail, providing a more comprehensive experimental basis and theoretical support for research and practical application in high-power electronic devices.</p></div>","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"34 6","pages":"4564 - 4572"},"PeriodicalIF":2.2,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143845681","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the compatibility issue arises between metal and plastic additive manufacturing technologies due to their substantial discrepancy in process temperatures. This paper explores refining fused deposition modeling by investigating the impact of copper electroless plating on 3D printed acrylonitrile butadiene styrene (ABS) parts. Electroless plating, a form of chemical metal deposition unlike conventional methods deposits metal without an electrical current. The 3D printed structure undergoes direct immersion in a copper (Cu) electroless plating bath, ensuring strong uniform adhesion. The research addresses challenges associated with ABS porosity and roughness, with a particular emphasis on surface preparation, adhesion, and dimensional stability. The proposed plastic 3D printing technology, combined with electroless plating, eliminates the need for etching or roughening of the ABS structure. Assessment criteria include ASTM standard surface finish and mechanical behavior (tensile, flexural, and hardness). Scanning electron microscopy reveals uniform copper plating, and results indicate superior mechanical properties and surface roughness in copper plated ABS specimens compared to non-plated ones. The research article highlights a remarkable improvement in mechanical properties post-electroless plating, with increases in tensile strength by approximately 81%, compression strength by 37%, Shore D hardness by 39%, and impact resistance by 81%, alongside a notable reduction in surface roughness by approximately 92.5%, affirming the efficacy of the plating process in enhancing material performance and surface quality. The findings offer crucial insights for ASTM-compliant FDM 3D printing advancements.</p></div>","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"34 5","pages":"3811 - 3818"},"PeriodicalIF":2.2,"publicationDate":"2025-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143668401","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The resulting wear and release of thermal energy causes failures of engines. It leads to a decrease in the performance of the mechanical system and energy loss. Among the effective ways to control these problems, lubrication is particularly important. Nowadays, adding nano-additives such as pure metals, metal oxides, metal sulfides, and carbon allotropes improves the tribological properties of lubricants. In fact, due to their potential for emission reduction and improving fuel economy, they are widely used as lubricant additives. Among nano-additives, molybdenum disulfide (MoS<sub>2</sub>) is extensively applied as a lubricant additive due to its unique properties. But what is very important is the high dispersibility of the nano-additive in the base oil, which directly affects the tribological properties of oils. Therefore, more favorable results can be expected by overcoming the tendency to accumulate MoS<sub>2</sub>. So, we synthesized carbon-based nanocomposites (NCs) of MoS<sub>2</sub> to spread on a suitable substrate, thus preventing their accumulation and using the synergistic effect of carbon materials in lubrication. MoS<sub>2</sub> was synthesized through two different methods, providing non-identical morphologies for MoS<sub>2</sub>. Using the one-step hydrothermal method, we grew nanoflowers-like MoS<sub>2</sub> (NFLs-MoS<sub>2</sub>) on a carbon substrate. MoS<sub>2</sub> with nanosheet morphology (NSs-MoS<sub>2</sub>) was synthesized using the hydrothermal method and then spreads on carbon substrate by calcination. The tribological properties of synthesized NCs are much better than pure MoS<sub>2</sub> and carbon bases.</p></div>","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"34 5","pages":"4125 - 4142"},"PeriodicalIF":2.2,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143668065","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the wear resistance is often insufficient for demanding applications. Therefore, an additional surface hardening step by thermochemical processes, in particular by gas nitriding, is promising for enhancing surface functionality. The characteristic porosity of thermally sprayed coatings facilitates deep nitrogen diffusion increasing hardness and wear resistance, due to the formation of precipitates. Because nitrides are thermally stable, applications at elevated temperatures are enabled. The process combination was examined for the ferritic stainless-steel AISI 431 applied on mild steel by high-velocity oxygen fuel spraying (HVOF), followed by subsequent gas nitriding. The influence of the thermochemical treatment with respect to a variation in the nitriding potential has been determined in terms of microstructure, phase formation, hardness distribution as well as reciprocating wear resistance at room and elevated temperature. The increase in hardness over 900 HV0.01 and wear resistance with wear rates consistently lower than 1.3 × 10<sup>-4</sup> mm<sup>3</sup> Nm<sup>−1</sup> can be attributed to the successful enrichment of nitrogen and the formation of mainly Fe<sub>4</sub>N precipitates at the coating’s surface.

The stochastic model describing the evolution of dislocation populations and grain size, which considers the random phenomena occurring during the hot forming of metallic alloys, was extended by including phase transformations during cooling. Accounting for a stochastic character of the nucleation of the new phase is the main feature of the model. Steel was selected as an example of the metallic alloy and equations describing the nucleation probability were proposed for ferrite, pearlite and bainite. The accuracy and reliability of the model depends on the correctness of the determination of the coefficients corresponding to the specific material. In the present paper these coefficients were identified using the inverse analysis for the experimental data. Experiments composed constant cooling rate tests for cooling rates in the range 0.1-20 °C/s. The inverse approach to a nonlinear model is ill-conditioned and must be transferred into an optimization problem, which requires formulating the appropriate objective function. Since the model is stochastic, it was a crucial, yet demanding task. The objective function based on a metric of the distance between measured and calculated histograms was proposed to achieve this goal. The original stochastic approach to identifying the phase transformation model for steels was tested, and an appropriate optimization strategy was proposed.</p></div>","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"33 24","pages":"13787 - 13802"},"PeriodicalIF":2.2,"publicationDate":"2024-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11665-024-10458-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142826330","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
