In this way, the quality of the liquid metal and the castings produced from it can be affected by the impurity content of the ingots used as charge material. In this work, a modified reduced pressure test (RPT) technique, which is based on the remelting of samples extracted from ingots, was applied to investigate the quality of primary AlSi9Mn ingots made by horizontal direct-chill (HDC) casting and gravity casting techniques. For the evaluation of metal quality, image analysis of the cross sections was applied. Pore area fraction, number density, normalized bifilm index, and normalized total pore perimeter were determined, and the relationships between the different metrics were analyzed. The results were compared with the melt quality assessment of the as-melted batches made from the ingots. Solidification simulations, thermal analysis, and microstructural investigations were conducted to investigate the solidification conditions of traditional and remelted RPT samples. Based on the results, the HDC cast ingots possess lower oxide and gas concentrations, which can be traced back to the differences in the melt preparation and casting technologies of the ingots. The comparison of the parameters evaluated by image analysis revealed that there is a strong linear relationship between normalized bifilm index and normalized total pore perimeter. The possible sources of error in ingot quality evaluation are highlighted.}, year = {2023}, eissn = {2163-3193}, orcid-numbers = {Gyarmati, Gábor/0000-0001-7568-6922} } @article{MTMT:33756830, title = {Reverse Engineering of Artefacts}, url = {https://m2.mtmt.hu/api/publication/33756830}, author = {Molnár, Dániel}, journal-iso = {LIVARSKI VESTNIK}, journal = {LIVARSKI VESTNIK}, volume = {70}, unique-id = {33756830}, issn = {0024-5135}, year = {2023}, pages = {16-34} } @misc{MTMT:33748835, title = {Innovatív alumínium öntészeti technikák}, url = {https://m2.mtmt.hu/api/publication/33748835}, author = {Molnár, Dániel and Kéri, Zoltán and Erdélyi, János Péter}, unique-id = {33748835}, year = {2023} }
