“…14c) indicates a cubic structure with an Im space group, which is consistent with the Al 19 Fe 4 MnSi 2 phase. The lattice parameter was determined to be 1.257 nm, which was in good agreement with that reported by [27]. Figure 15 shows the high-resolution transmission electron micrographs (HRTEM) and corresponding SAED of the M4 sample.…”

This work demonstrates that the combined addition of Al10Sr and Al5TiB master alloys to the AlMg5Si2Mn effectively refines the grain microstructure and partially modifies the eutectic Mg2Si phase. Thorough spectroscopic characterization reveals that the grain refinement effect is due to Al3Ti particles acting as nucleation sites for α-Al grains, and the increased nucleation temperature of α-Al is due to Al10Sr addition. It is also determined that TiB2 particles can act as nucleation substrates for the primary Mg2Si phase. The prepared alloy sample with the finest microstructure (treated with both Al10Sr and Al5TiB) exhibits the greatest corrosion resistance among all tested samples.

“…Tests were carried out on AlCu4MgSi (EN AW-2017A) alloy ingots (30 mm in diameter), which were produced using an aluminium alloys horizontal continuous casting test stand, located in the technological laboratory of the Department of Foundry Engineering at Silesian University of Technology. Detailed description of implemented horizontal continuous casting process and parameters is presented in previous works of the authors [11,12].…”

The article presents the results of research concerning to AlCu4MgSi alloy ingots produced using horizontal continuous casting process. The presented research was focused on the precise determination of phase composition of the precipitates formed during the solidification of ingots and the analysis of their thermal stability. In order to assess the morphology of precipitates in the AlCu4MgSi alloy, data obtained by using a computer simulation of thermodynamic phenomena were compiled with results obtained using advanced research techniques, i.e. High-temperature X-ray diffraction (HT-XRD), SEM-EDS, Thermal and derivative analysis (TDA) and Glow discharge optical emission spectroscopy (GD OES). SEM observations and analysis of chemical composition in micro-areas showed that the precipitates are mainly intermetallic θ-Al 2 Cu and β-Mg 2 Si phases, and also presence of Al 19 Fe 4 MnSi 2 intermetallic phase was confirmed by X-ray diffraction studies. Based on the prepared Thermo-Calc simulation data, high-temperature X-ray diffraction measurements were conducted.

“…The both studied Al alloys were obtained as 30 mm ingots in a horizontal continuous casting process. Detailed description of implemented horizontal continuous casting process is presented in paper [13] and [14] respectively, for the studied Al-Si and Al-Cu alloys. In detail in studies were used samples of ingots with dimensions: 30mm in diameter and 15mm high in the amount of two pieces for each variant of heat treatment.…”

The paper presents the research results of the influence of the precipitation hardening on hardness and microstructure of selected Al-Si and Al-Cu alloys obtained as 30 mm ingots in a horizontal continuous casting process. The ingots were heat treated in process of precipitation hardening i.e. supersaturation with subsequent accelerated or natural ageing. Moreover in the range of the study it has been carried out investigations of chemical constitution, microscopic metallographic with use of scanning electron microscope with EDS analysis system, and hardness measurements using the Brinell method. On basis of obtained results it has been concluded that the chemical constitution of the investigated alloys enables to classify them into Al alloys for the plastic deformation as EN AW-AlSi2Mn (alternatively cast alloy EN AC-AlSi2MgTi) and as EN AW-AlCu4MgSi (alternatively cast alloy EN AC-AlCu4MgTi) grades. Moreover in result of applied precipitation hardening has resulted in the precipitation from a supersaturated solid solution of dispersive particles of secondary phases rich in alloying element i.e. Si and Cu respectively. In consequence it has been obtained increase in hardness in case of AlSi2Mn alloy by approximately 30% and in case of AlCu4MgSi alloy by approximately 20% in comparison to the as-cast state of continuous ingots.
