Although many different alloys were already developed in the past, additive manufacturing like laser powder bed fusion (PBF-LB/M) opens up new possibilities for alloy development, mainly driven by the very high cooling rates. This allows for the usage of precipitation-hardened alloys with compositions exceeding the maximum solubility. The present work focuses on the investigation of a well-known CuCr1Zr alloy as well as CuZr alloys with 1 and 2 wt.% Zr. For a fast, resource-efficient screening and demonstration of feasibility, the investigated alloys were not printed from powder. Instead, solid sheets were partially re-melted in a PBF-LB/M machine to obtain a microstructure similar to the printed state. This rapid-solidification microstructure is investigated, and precipitates with a size 50 nm or even smaller are found. After subsequent aging heat treatments, the hardness of the alloys exceeds the maximum hardness achievable with conventional manufacturing methods (excluding work hardening). The investigations in this work revealed the great hardening potential of these alloys for usage in the PBF-LB/M process.","PeriodicalId":36643,"journal":{"name":"Progress in Additive Manufacturing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135870679","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Water-soluble casting molds offer a promising solution to overcome those restrains, for example by hot pressing of salt cores or 3D printing of NaCl molds. Presently, 3D printing techniques available for NaCl are limited to direct ink writing (DIW) and photopolymerization. This study presents an approach to prepare NaCl parts by thermoplastic material extrusion (MEX) 3D printing. Firstly, a 3D printable feedstock is developed consisting of an organic binder, which is usually used for ceramic injection molding, and sodium chloride (NaCl) salt crystals. Various molds are then printed on a granulate-fed MEX printer. After thermal debinding and sintering at 690 °C, the 3D printed parts consist of pure NaCl. Furthermore, the same NaCl feedstock is used for injection molding. The bending strength of 3D printed samples with and without post-treatment are measured and compared to injection molded test specimens. Finally, metal casting in 3D printed NaCl molds is shown with tin or aluminum and the metal demonstrator parts with complex geometries such as gyroid structures and turbine wheels are released by dissolving the NaCl molds in water.","PeriodicalId":36643,"journal":{"name":"Progress in Additive Manufacturing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136134592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
