The phase diagram of the Al−Ca−Fe system in aluminum corner, including liquidus projection and solidification reactions, was studied by using thermodynamic calculations experimental techniques. results show that instead Al3Fe phase, a ternary compound whose composition corresponds to formula Al10CaFe2 should be equilibrium with solid solution (Al). Thе transition from binary occurs via peritectic transformation L + → (Al) (at 638 °C, 3.3 at.% Ca 0.5 Fe). Primary eutectic crystals have...
In the present paper, Natural Metal-Matrix Composites (NMMC) based on multicomponent hypereutectic Al-Ca-(Mn)-(Ni) alloys were studied in as-cast, annealed and rolled conditions. Thermo-Calc software microstructural observations utilised for analysing equilibrium actual phase composition of including correction Al-Ca-Mn system liquidus projection solid distribution Al-Ca-Mn-Ni system. A previously unknown Al10CaMn2 was discovered by both electron microprobe analysis X-ray studies. The...
The phase transformations in the Al-Ca-Mg-Si system have been studied using thermodynamic calculations and experimental methods. We show that at 10% Magnesium (Mg), depending on concentrations of calcium (Ca) silicon (Si), following phases crystallize first (apart from aluminum (Al) solid solution): Al4Ca, Mg2Si, Al2CaSi2. found major part calculated concentration range is covered by region primary crystallization Al2CaSi2 phase. Regardless Ca Si content, solidification aluminum-magnesium...
Investigating the effect of Fe and Si is essential for any new Al-based composition, as these impurities can be easily found both after primary production recycling. This study dedicated to filling gap in revealing phase composition an Al-6%Mg-2%Ca-2%Zn alloy combined separate addition Si. was addressed by permanent mold casting solid solution heat treatment. The investigation slowly solidified samples also contributed understanding potential transitions. It that containing 0.5%Fe have...
The phase composition, rolling processability and mechanical properties of the experimental Al3Mg2Ca0.8Mn alloy were studied. microstructure as-cast ingots contained aluminum matrix a branched network multiphase eutectics which consisted 4 phases according to our calculations, i.e., (Al), Al6(Mn,Fe), Al4Ca andAl3Mg2. average size eutectic intermetallic particles was approx. 6 mm. Subsequent homogenization annealing caused significant fragmentation spheroidization inclusions, leading...
Ceramic coatings were formed on the surface of as-cast Al5.2Zn1.7Mg0.4Ni0.3Fe and heat-treated Al7.0Zn2.7Mg0.5Ni0.4Fe “nikalin” aluminum alloys by using plasma electrolytic oxidation (PEO) technique in a silicate–alkaline electrolyte. Uniform containing minimum number defects consisting predominantly γ-Al2O3 phase synthesized both Al-Zn-Mg-Ni-Fe alloys. The had microhardness 660–1200 HV, which is 3.5–11 times higher than that “bare” alloy. coating Al5.2Zn1.65Mg0.4Ni0.3Fe alloy highest peak...
