Item type:Presentation, Access status: Open Access , The influence of furfuryl resin type – classical and designed for sand 3D printing, on cast iron castings microstructure and surface roughness(2025) Major-Gabryś, Katarzyna; Halejcio, Dawid; Fijołek, Andrzej; Marosz, Jan; Górny, Marcin
Wydział OdlewnictwaThis conference abstract shows the results achieved within NetCastPL4.0 project. The project is being realized in cooperation between AGH Faculty of Foundry Engineering (Leader), CNR-ICMATE and Aalto University School of Engineering. This work, presented during the V International Conference of Casting and Materials Engineering ICCME 25 in Krakow, Poland on October 27-28, 2025, describes the research on molding sands for molds and cores 3D printing. The work concerns the influence of furfuryl resin type (classical and designed for 3D printing) on cast iron castings properties. The pouring parameters were elaborated on the basis of MAGMA software. The microscopic observations of castings, produced in classical and 3D printed molds were conducted as well as roughness of the samples assessment.Item type:Presentation, Access status: Open Access , The use of green molding materials in the production of advanced lightweighting castings(2025) Major-Gabryś, Katarzyna; Drożyński, Dariusz; Górny, Marcin; Marosz, Jan; Lelito, Janusz

The project is being realized in cooperation between AGH Faculty of Foundry Engineering (Leader), CNR-ICMATE and Aalto University School of Engineering. This work, presented during the V International Conference of Casting and Materials Engineering ICCME 25 in Krakow, Poland on October 27-28, 2025, describes the research connected with the development of molding compounds for thin-walled castings. Two compounds with organic binders and two compounds with inorganic binders of self-curing molding sands were tested. Tests were carried out on the tensile and bending strength, permeability, and friability of the compounds. For selected molding sands, tests were carried out on their thermophysical properties (hot distortion parameter), gas emission, and thermal degradation. For castings production also molds produced using additive manufacturing (3D printing technology) were used.Item type:Article, Access status: Open Access , The effect of nickel on shaping the structure of Al-Cu-Mn alloys(2017) Górny, Marcin; Sikora, Gabriela; Tyrała, Edward; Repeć, PawełThis study investigated the effect of nickel on shaping the structure of aluminum alloys of the Al-Cu-Mn type in the »as-cast« condition and after heat treatment according to the T6 procedure. The aluminum alloys of type Al-5%Cu-1%Mn, containing nickel in a range of up to 1.9%, were taken into consideration in this work. Experiments were carried out for thin-walled thickness casting (g = 5 mm) and for reference casting with a wall thickness of g = 35 mm. Metallographic investigations of both the macro- and micro-structure were conducted to estimate the secondary dendrite arm spacing (SDAS), average diameter (dav) of the primary α (Al) grains, and surface fraction of the interdendritic phases (f). Moreover, the degree of dissolution of these interdendritic phases during the solution treatment process was determined. An SEM-EDS analysis was conducted, from which it follows that the addition of nickel at the level of 0.5% changes the un-dissolved particles from a needle-like β-Fe shape to blocky and coagulated. Higher additions of nickel starting from 0.88%) give rise to as many as four phases with higher copper content, the deficit of which results in the smaller strengthening effect of α (Al) dendrites.Item type:Presentation, Access status: Open Access , The use of green molding materials in the production of advanced lightweighting castingsMajor-Gabryś, Katarzyna; Drożyński, Dariusz; Górny, Marcin; Marosz, Jan; Lelito, Janusz
