This study is aimed at applying existing calculation methods for pressure-loaded parts to additively manufactured pipe structures, considering the two materials EN AC-43000 (3.2381, AlSi10Mg) and AISI 316L (1.4404, X2CrNiMo17-12-2). For this purpose, systematic tensile tests are carried out for both materials. In addition, a statistical evaluation is performed to determine the design-relevant strength characteristics with a survival probability Ps of 97.5 % for both materials in the as-built and heat-treated condition.\r\nPipe specimens are manufactured, half of which are heat treated, geometrically measured and then subjected to a burst pressure test to experimentally determine the failure-critical internal pressure. These results are compared with calculated burst pressures. The calculations are based on the application-relevant methods identified in this study, considering the strength values determined for the respective material condition. This comparison is used to assess the suitability of the calculation methods for additively manufactured pipe structures, based on the materials investigated."}],"keyword":["PBF-LB/M","Pipe structures","Strength assessment","Burst pressure test","Geometrical deviations"],"language":[{"iso":"eng"}],"quality_controlled":"1","year":"2026","publisher":"Elsevier BV","date_created":"2026-01-07T08:39:04Z","title":"Analytical and experimental determination of the failure-critical pressure of pipe structures manufactured by PBF-LB/M","type":"journal_article","status":"public","_id":"63512","user_id":"97759","department":[{"_id":"146"},{"_id":"9"},{"_id":"624"},{"_id":"149"},{"_id":"321"}],"article_number":"105753","publication_status":"published","publication_identifier":{"issn":["0308-0161"]},"citation":{"ieee":"T.

Preparation of these alloys by twin-roll casting (TRC), which combines rapid metal solidification and subsequent plastic reduction in a single processing step, could improve the properties of the alloys compared to materials prepared by conventional direct-chill casting. A commonly used approach for identifying primary phases is a chemical analysis by energy dispersive spectroscopy (EDS). More accurate results can be achieved by combining the method with diffraction analysis. This process can be considerably simplified in microscopes equipped with automated crystal orientation and phase mapping (ACOM-TEM). Al-Cu-Li-Mg-Zr alloy was prepared by twin-roll casting. A combination of TEM and STEM images with chemical analysis by EDS and ACOM-TEM was used to obtain complex information about phases of boundary primary particles.

Unfortunately, high-strength aluminum alloys such as AA7075 are prone to hot cracking during PBF-LB/M, as well as welding. Both a large solidification range promoted by the alloying elements zinc and copper and a high thermal gradient accompanied with the manufacturing process conditions lead to or favor hot cracking. In the present study, a simple method for modifying the powder surface with titanium carbide nanoparticles (NPs) as a nucleating agent is aimed. The effect on the microstructure with different amounts of the nucleating agent is shown. For the aluminum alloy 7075 with 2.5 ma% titanium carbide nanoparticles, manufactured via PBF-LB/M, crack-free samples with a refined microstructure having no discernible melt pool boundaries and columnar grains are observed. After using a two-step ageing heat treatment, ultimate tensile strengths up to 465 MPa and an 8.9% elongation at break are achieved. Furthermore, it is demonstrated that not all nanoparticles used remain in the melt pool during PBF-LB/M.","lang":"eng"}],"type":"journal_article","publication":"Materials","language":[{"iso":"eng"}],"file_date_updated":"2021-11-29T08:19:19Z","ddc":["620"],"keyword":["grain refinement","crack reduction","laser beam melting","aluminum alloy","titanium carbide","nanoparticle","PBF-LB/M"],"user_id":"77250","department":[{"_id":"9"},{"_id":"158"},{"_id":"219"}],"_id":"28017","citation":{"apa":"Heiland, S., Milkereit, B., Hoyer, K.-P., Zhuravlev, E., Keßler, O., &#38; Schaper, M.

Insbesondere im Bereich des Leichtbaus bieten zelluläre Strukturen neue Ansätze zur Verminderung des Energieverbrauchs. Um dieses Potential vollständig ausschöpfen zu können, müssen die Effekte, die zum Versagen der Bauteile mit integrierten Gitterstrukturen führen, quantitativ beschrieben und verstanden werden.
