The processing of magnesium alloys and the production of complex geometries is possible with laser beam powder bed fusion. However, the small material volume of the lattice structures and the magnesium alloy require specific process parameters in order to achieve a high quality of the material. Therefore, the influence of two perspective laser strategies (contour strategy and hatch strategy), their combination, and skywriting is investigated. The geometry of the body-centered-cubic (BCC) lattice structure is used, representing the most difficult lattice structure to produce due to the struts inclination. A relative material density of over 99% is achieved with three laser strategies. The laser strategies have a direct influence on the pore distribution, pore shape, and microstructure. All these parameters can influence the mechanical performance of the BCC structures. The best performance is achieved with the hatch strategy with skywriting, which results in a low number of dangerous pores and a fine microstructure. The Young's modulus of material of 40 GPa and the effective elastic modulus of BCC structure of 136 MPa are achieved.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"27 7","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adem.202402625","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143801685","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}

A peculiarity of gallium, compared to other metal fixed-points, is its high degree of supercooling which can limit its possible applications. However, in literature, different authors observed the suppression of supercooling in case of small gallium cells. The reason for this is not completely clear. In this article, the supercooling effect was investigated in the specific case of a miniature gallium cells designed for space applications. The results show that the degree of supercooling is function of the thermal history of the cell. As the temperature of the metal, in the liquid state, increased, a linear dependence between the overheating of the sample and the supercooling effect was observed. This relationship is particularly important when the cell must be used to perform subsequent calibration cycles. An understanding of the factors that govern the supercooling, as proposed in this study, could help to develop ways to control it, in the design of calibration systems, and procedures to be used in different applications.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"27 7","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adem.202402763","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143801687","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 effects of different layer numbers on the structural, mechanical, tribological, adhesion, and fatigue properties of TiNi/Ti2AlN multilayer films are investigated. All films’ thickness is measured to be ≈2 μm. The 20 layers film deposited on Inconel 718 exhibited the best mechanical properties, with a hardness of 30.6 GPa and an elastic modulus of 407 GPa. A significant improvement in the tribological performance of the films is observed with an increasing number of layers. The lowest wear rate, calculated as 1.96 × 10−5 (mm3 (N·m)−1), is observed for the 20 layers film deposited on Inconel 718 at room temperature. At high temperatures, the friction coefficients of the 16 and 20 layers films deposited on Inconel 718 decreased to 0.25. In terms of adhesion properties, the 10 layers films deposited on AISI M2 steel demonstrated the best performance with a critical load value of 45 N.

After the production of a large number of such recycled magnets, these are installed in the demonstrators. Measurements on various test benches show that the demonstrators with recycled or reused magnets exhibit across the entire rotation speed range a similar or higher electromotive force or induced voltage as compared to their counterparts with primary magnets. While the e-Scooter motor achieves almost the same induced voltage (–0.7%) by using recycled magnets, the Hoverboard motor shows even an increased voltage of 6.7%. In the case of the Pedelec motor, the reuse of EoL-magnets leads to a voltage increase of 0.9% compared to the use of primary magnets.

This study investigates the effects of varying anodization parameters on TiO2 nanotubes, nanograss, and nanolace formation. Field-emission scanning electron microscopy is employed to analyze these nanostructures’ morphology and growth rates. The structural characteristics of the resulting nanostructures are precisely controlled by adjusting temperature, water content, duration, and applied potential during the anodization process. Nanotube length and diameter are influenced by ethylene glycol (EG) concentration, applied voltage, and temperature. The quantity of nanograss is determined by the anodization temperature. Nanolace formation is affected by hydrofluoric acid (HF) pretreatment of titanium foil. The results demonstrate that higher EG concentrations and applied potentials produce longer nanotubes, whereas lower EG concentrations with higher potentials result in larger nanotube diameters. Temperature variations control the amount of nanograss. HF pretreatment facilitates the formation of a hexagonal nanolace network on the surface. By tailoring synthesis conditions, this study provides a method for controlling the morphology of TiO2 nanostructures. These findings have implications for optimizing TiO2 nanostructures in sensors, photocatalysis, and other areas of nanotechnology, where specific structural properties are crucial for enhanced performance.","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"27 7","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adem.202402227","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143801502","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}
