The thermal cycles that are unique and specific to AM limit the applicability of research from casting literature under some circumstances. In this work, single-track and multitrack laser glazing experiments performed on four unique suction cast glass-forming compositions provide a means for screening the suitability and relative process window sizes for powder bed fusion–laser beam (PBF–LB) AM of four GFAs in the absence of available powders. The crystallinity of the fusion zone and the HAZ as well as the presence of cracks are observed as process parameters are varied for each alloy. Both conventionally good and conventionally bad glass formers show great potential for PBF–LB processability. Glass-forming ability in and of itself is not a good predictor of PBF–LB printability.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"27 9","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adem.202402214","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143909269","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}

The thermal gravimetric analysis reveal that the single MoSi2 coating initially exhibits a stable mass change (–3.7 mg cm−2) for ≈37 cycles, followed by a rapid increase in mass gain (2.2 mg cm−2 after 100 cycles). The 50% Ti3SiC2/MoSi2 composite coating demonstrated linear oxidation kinetics with a mass gain of 3.5 mg cm−2 after 100 cycles. Notably, the 10% Ti3SiC2/MoSi2 composite coating showed superior stability, with minimal mass gain (–2.7 mg cm−2) over 100 cycles. The scale formed on the 10% coatings is characterized as compact, dense, and firmly adhered to the substrate, primarily consisting of an amorphous SiO2 matrix interspersed with fine TiO2 grains.

Wear resistance improves through grain refinement, dislocation hindrance, and hard reinforcing phases, while corrosion resistance benefits from blocked corrosion pathways. Nickel-copper (NiCu) and 3, 6, and 9 wt% nanotungsten carbide/nickel copper (WC/NiCu) deposition specimens are prepared by the directed energy deposition technique. Lattice dispersion strengthening, solid solution strengthening, and fine grain strengthening synergistically increase the microhardness of NiCu alloys, and the microhardness of 6 wt% nano-WC/NiCu is increased by 16.3% compared to NiCu-deposited specimens. The coefficient of friction is reduced by 11.1% and the amount of wear is reduced by 84.87% in the ring-block friction and wear experiments at a loading of 150 N. This increase in wear resistance is attributed to the increase in overall hardness and the formation of a hard protective layer of tungsten carbide (WC) within the composite-deposited specimen. The composite's corrosion resistance improves with 29.9% lower corrosion current and 111.2% higher polarization resistance, as precipitated carbides and dense grain boundaries block corrosion channels.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"27 9","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143909134","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 weld metal (WM) primarily comprises interlocking lath bainite and lath martensite, with small amounts of granular bainite and retained austenite in the heat-affected zone (HAZ). The tensile strength, yield strength, and elongation of the welded joints are 1084, 1022 MPa, and 17%, respectively. Both the WM and HAZ have high impact toughness at temperatures of 20 to −80 °C. The HAZ has higher toughness than the WM because of its higher content of retained austenite and high-angle grain boundaries. These factors significantly obstruct crack growth, resulting in good toughness of the entire joint. The critical crack tip opening displacement for the HAZ (0.229 mm) is significantly higher than that of the WM (0.079 mm), indicating that the fracture toughness of the HAZ surpasses that of the WM, which is consistent with the Charpy impact results.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"27 9","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143909225","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}

However, limited studies have focused on the deformation behavior and mechanisms under combined high strain rates and high temperatures. In this study, uniaxial compression experiments were conducted on a typical bimodal L12 precipitates strengthened nickel superalloy over a wide range of temperatures (293–1273 K) and strain rates (1 × 10−3 s−1–5 × 103 s−1) to reveal the coupling effect of temperature and strain rate on the mechanical behavior. The results show that the mechanical behavior is highly sensitive to temperature and strain rate, with the alloy exhibiting remarkable high temperature strength, particularly under dynamic loading. The third-type strain aging (3rd SA) effect is observed in this alloy, and its underlying mechanism is analyzed. Microstructural characterizations are conducted at various conditions, providing multiscale insight into the intricate relationship between microstructure and property. A transition in dominant deformation mechanisms is observed, shifting from anti-phase boundary dislocation pair shearing to stacking fault as temperature increases. Additionally, a comprehensive diagram is provided to elucidate the deformation mechanisms of the alloy under a wide range of strain rates and temperatures.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"27 9","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143909135","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 focus is on optimizing key process parameters—wire feeding speed, interlayer temperature, protective gas flow rate, and welding wire elongation—to minimize porosity and splash. A comprehensive analysis of parameter interactions is conducted using contour maps and response surface plots. The findings indicate that wire elongation most significantly affects porosity, while wire feeding speed has the greatest impact on splash.

Here, we present for the first time the possibility of maskless metallization of a curved surface using direct laser metallization (DLM) from deep eutectic solvents (DES). The degree of shading, scanning speed, and number of scans were optimized for glass substrates with varying degrees of curvature. The obtained copper pattern have controlled roughness, excellent stability, and adhesion. A new milestone was achieved for deposition rate for this method (−18.8 mm s−1).
