Elemental metal powders were mixed in a planetary ball mill and directly deposited to investigate the effect of layer number on alloy composition and substrate intermixing. Experimental results revealed significant dilution in the first four layers, with substrate intermixing affecting composition. The coarse-grained crystal structure observed in the initial layers persisted in subsequent layers, and hardness measurements indicated the cumulative thermal effects of sequential deposition. From an industrial perspective, this approach offers a cost-effective and flexible manufacturing strategy, eliminating the need for pre-alloying. Moreover, gradient compositional layers can be achieved, enabling tailored material properties. This work demonstrates the feasibility of producing multi-layer HEAs directly from elemental powders while addressing the challenges of compositional stability.}, year = {2025}, eissn = {2079-6412}, orcid-numbers = {Windisch, Márk/0009-0004-3413-2471; Vida, Ádám/0000-0002-0519-2772} } @article{MTMT:36298327, title = {Effect of Chemical Etching on the Supercapacitive Performance of Electroless Ni-B Coatings}, url = {https://m2.mtmt.hu/api/publication/36298327}, author = {Czagány, Máté and Mészáros, Gábor and Koncz-Horváth, Dániel and Hlavács, Adrienn and Windisch, Márk and Hwang, B. and Baumli, Péter}, doi = {10.3390/ma18153544}, journal-iso = {MATERIALS}, journal = {MATERIALS}, volume = {18}, unique-id = {36298327}, year = {2025}, eissn = {1996-1944}, orcid-numbers = {Windisch, Márk/0009-0004-3413-2471} } @article{MTMT:34258392, title = {X-ray line profile analysis study on the evolution of the microstructure in additively manufactured 316L steel during severe plastic deformation}, url = {https://m2.mtmt.hu/api/publication/34258392}, author = {Gubicza, Jenő and Kawasaki, M. and Dankházi, Zoltán and Windisch, Márk and El-Tahawy, Moustafa}, doi = {10.1007/s10853-023-09030-0}, journal-iso = {J MATER SCI}, journal = {JOURNAL OF MATERIALS SCIENCE}, volume = {59}, unique-id = {34258392}, issn = {0022-2461}, year = {2024}, eissn = {1573-4803}, pages = {6008-6023}, orcid-numbers = {Gubicza, Jenő/0000-0002-8938-7293; Dankházi, Zoltán/0000-0001-9545-2015; Windisch, Márk/0009-0004-3413-2471} } @article{MTMT:34562195, title = {3D printing parameters optimization for Fe-6.5 wt%Si}, url = {https://m2.mtmt.hu/api/publication/34562195}, author = {Kocsis, Bence and Windisch, Márk and Mészáros, István and Varga, Lajos Károly}, doi = {10.1016/j.jmmm.2024.171829}, journal-iso = {J MAGN MAGN MATER}, journal = {JOURNAL OF MAGNETISM AND MAGNETIC MATERIALS}, volume = {592}, unique-id = {34562195}, issn = {0304-8853}, year = {2024}, eissn = {1873-4766}, orcid-numbers = {Kocsis, Bence/0000-0003-4751-5071; Windisch, Márk/0009-0004-3413-2471} } @article{MTMT:34892226, title = {Nanostructuring of an additively manufactured CoCrFeNi multi-principal element alloy using severe plastic deformation: Comparison of two materials processed by different laser scan speeds}, url = {https://m2.mtmt.hu/api/publication/34892226}, author = {Mukhtarova, Kamilla and Kawasaki, M. and Dankházi, Zoltán and Windisch, Márk and Radnóczi, György Zoltán and Serafimowicz, W. and Gubicza, Jenő}, doi = {10.1016/j.intermet.2024.108336}, journal-iso = {INTERMETALLICS}, journal = {INTERMETALLICS}, volume = {170}, unique-id = {34892226}, issn = {0966-9795}, abstract = {Experiments were conducted to reveal the refinement of the microstructure and the evolution of the hardness of an additively manufactured (AM) CoCrFeNi multi-principal element alloy (MPEA) processed by severe plastic deformation (SPD) using high pressure torsion (HPT) technique. AM was carried out by laser powder bed fusion (L-PBF) technique at two different laser scan speeds. The as-built alloys for both laser scan speeds have a single-phase face-centered cubic (fcc) structure with <110> fiber texture parallel to the building direction. X-ray line profile analysis (XLPA) revealed that the dislocation density was considerably high even in the AM-processed state before HPT (3 × 1014 m 2) which increased by two orders of magnitude during HPT. The saturation of the lattice defects (dislocation density and twin fault probability) as well as the crystallite size occurred at a shear strain of about 10 during HPT. In both AM-processed alloys, <111> fiber texture developed parallel to the normal of the HPT-processed disks. For both laser scan speeds, the initial grain size in the AM-processed samples was refined from 70 to 90 μm to the nanocrystalline regime after 10 turns of HPT. Additionally, nanotwins formed with a probability of about 3 %. The initial hardness of the AM-processed MPEA samples for both laser scan speeds was 2700–2800 MPa, which is superior to that of CoCrFeNi produced by casting (about 1380 MPa). This can be explained by the high dislocation density in the AM-processed specimens. The formation of nano-structure with high lattice defect density during HPT resulted in a very high hardness value of about 5500 MPa in the AM-processed CoCrFeNi MPEA samples for both laser scan speeds.}, year = {2024}, eissn = {1879-0216}, orcid-numbers = {Dankházi, Zoltán/0000-0001-9545-2015; Windisch, Márk/0009-0004-3413-2471; Radnóczi, György Zoltán/0000-0002-7106-6272; Gubicza, Jenő/0000-0002-8938-7293} } @article{MTMT:35143692, title = {Investigation of Ripple Formation on Surface of Silicon by Low-Energy Gallium Ion Bombardment}, url = {https://m2.mtmt.hu/api/publication/35143692}, author = {Windisch, Márk and Selmeczi, Daniel and Vida, Adam and Dankházi, Zoltán}, doi = {10.3390/nano14131124}, journal-iso = {NANOMATERIALS-BASEL}, journal = {NANOMATERIALS}, volume = {14}, unique-id = {35143692}, keywords = {SILICON; ion bombardment; Ellipsometry; Amorphous layer; ripple formation}, year = {2024}, eissn = {2079-4991}, orcid-numbers = {Windisch, Márk/0009-0004-3413-2471; Dankházi, Zoltán/0000-0001-9545-2015} } @article{MTMT:35182649, title = {Transformation of Biomass Power Plant Ash into Composite Fertilizers: A Perspective to Prepare a Rain-Controlled Ammonium Ion–Releasing Composite Fertilizer}, url = {https://m2.mtmt.hu/api/publication/35182649}, author = {Kótai, László and Windisch, Márk and Béres, Kende Attila}, doi = {10.3390/jcs8090336}, journal-iso = {J COMPOSITES SCI}, journal = {JOURNAL OF COMPOSITES SCIENCE}, volume = {8}, unique-id = {35182649}, issn = {2504-477X}, abstract = {We have developed a convenient route to transform biomass power plant ashes (BPPA) into porous sponge-like fertilizer composites. The absence of water prevents the chemical reaction and carbon dioxide formation when concentrated sulfuric acid is mixed with BPPA and CaCO3. Adding water, however, initiates the protonation reaction of carbonate ion content and starts CO2 evolution. The key element of the method was that the BPPA and, optionally, CaCO3 and/or CaSO4·0.5H2O were mixed with concentrated sulfuric acid to make a paste-like consistency. No gas evolution occurred at this stage; however, with the subsequent and controlled addition of water, CO2 gas evolved and was released through the channels developed in the pastry-like material due to the internal gas pressure, but without foaming. Using a screw-containing tube reactor, the water can be introduced under pressure. Due to the pressure, the pores in the pastry-like material became smaller, and consequently, the mechanical strength of the granulated and solidified mixture became higher than that of the reaction products prepared under atmospheric pressure. The main reaction products were syngenite (K2Ca(SO4)2·H2O) and polyhalite (K2Ca2Mg(SO4)4·2H2O). These compounds are valuable fertilizer components in themselves, but the material’s porous nature helps absorb solutions of microelement fertilizers. Surprisingly, concentrated ammonium nitrate solutions transform the syngenite content of the porous fertilizer into ammonium calcium sulfate ((NH4)2Ca(SO4)2·2H2O, koktaite). Koktaite is slightly soluble in water, thus the amount of ammonium ion released on the dissolution of koktaite depends on the amount of available water. Accordingly, ammonium ion release for plants can be increased with rain or irrigation, and koktaite is undissolved and does not decompose in drought situations. The pores (holes) of this sponge-like fertilizer product can be filled with different solutions containing other fertilizer components (phosphates, zinc, etc.) to adjust the composition of the requested fertilizer compositions for particular soils and plant production. The method allows the preparation of ammonium nitrate composite fertilizers containing metallic microelements, and various solid sponge-like composite materials with adjusted amounts of slowly releasing fertilizer components like syngenite and koktaite.}, year = {2024}, eissn = {2504-477X}, orcid-numbers = {Windisch, Márk/0009-0004-3413-2471; Béres, Kende Attila/0000-0003-4257-0581} } @article{MTMT:34054991, title = {Investigation of the Supercapacitive Behavior of Electroless Ni-B Coatings}, url = {https://m2.mtmt.hu/api/publication/34054991}, author = {Czagány, Máté and Hompoth, Szabolcs and Windisch, Márk and Baumli, Péter}, doi = {10.3390/met13071233}, journal-iso = {METALS-BASEL}, journal = {METALS}, volume = {13}, unique-id = {34054991}, abstract = {Amorphous electroless Ni-B coatings were deposited on steel substrates with different surface morphologies and B contents (6.5–8.64 wt.%) that could be changed by altering the temperature and the composition of the baths. The supercapacitive behavior of the coatings was evaluated by cyclic voltammetry and galvanostatic charge–discharge measurements, and it was found that Ni-B coatings had higher capacitance than pure electroless Ni or the bulk Ni plate. A close relationship was identified between the microstructure, the B content, and the capacitive behavior of the coatings. The presence of the B alloying element had the most significant effect in determining the capacitance, while the surface area and particle size also contributed to its increase. A surface-specific capacity of 31 mF/cm2 was achieved by the coating containing the highest B content and largest AFM surface area. Furthermore, it was revealed that the particle size of the deposits was determined by the combined effect of the bath temperature and the B content under the applied experimental conditions.
