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.

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.</p>","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}
