“…[7] Phase diagrams are possible to calculate using several different CALPHAD-based programs e.g., ThermoCalc [17] or Pandat. [18] Relevant thermodynamic database can be used to calculate equilibrium phase diagrams of binary subsystems, here Sb-Sn, [9] Sn-Zn, [7] and Sb-Zn. [8] The method also allows us to predict the ternary phase diagram of the Sb-Sn-Zn system, as the authors used before [19] and here for better understanding of the obtained experimental results.…”

International. This e-offprint isExperimental Study of the Sb-Sn-Zn Alloy System ONDREJ ZOBAC, JIRI SOPOUSEK, JIRI BURSIK, ADELA ZEMANOVA, and PAVLA ROUPCOVA The Sb-Sn-Zn alloy was prepared and researched by experimental methods, which allow obtaining information on the thermodynamic stability of the coexisting phases. Thermal analysis was used to determine the phase transition temperatures of experimental alloys. Equilibrium composition of coexisting phases after long-term temperature equilibration was determined by electron microscopy. The existence of one ternary stoichiometric phase Sb 2 SnZn was experimentally confirmed by diffraction technique. The CALPHAD method for prediction of the phase diagram of the Sb-Sn-Zn system from binary subsystems was used in this work.

“…X-ray diffractometer was equipped with solid-state detector and operated at 1.6 kW Cu-K a radiation. Thermodynamic calculations were performed with CALculation of PHAse Diagram (CALPHAD) methodology using PandaT software [16] and image analysis were carried out using ImageJ software [17]. Tensile testing was carried out in selected specimens with 25 mm gauge length in compliance with ASTM B557-10 standard [18].…”

“…Primary production of aluminium from bauxite ore attracts an energy expenditure of about 186 MJ/kg of metallic aluminium; however, this expenditure could be reduced to [10][11][12][13][14][15][16][17][18][19][20] MJ/kg by recycling the discarded aluminium products or scraps [1,2]. These figures emphasize not only the economic importance but also the underlying environmental benefits in the favour of recycling aluminium scraps.…”

High iron impurity has detrimental effects on the castability and tensile properties of recycled aluminium alloys. The present study reports the engineering of intermetallic β-phase present in hypoeutectic cast Al-Si model alloy systems with high Fe content (2wt% Fe) in order to demonstrate the promising recyclability despite having high Fe content. Thermodynamic interplay between Si and Fe concentration on the formation of the β-phase and the solidification behaviour of the hypoeutectic Al-Si alloys has been explored. It has been demonstrated that with suitable heat treatment it is possible to alter the morphology of the β-phase and based on the experimental evidences, for the first time, the mechanism behind the solid-state morphological changes of beta phase has been proposed. Based on the experimental results and thermodynamic calculations it has been suggested that elimination of beta phase by gravitational segregation is more suitable for the near-eutectic 10wt% Si alloy; whereas for 6wt%Si alloy, morphological change of β-phase is recommended. It was also found that morphological change of beta-phase and Si could help recovering the strength and ductility in the recycled Al-Si alloys having high Fe content.

PHASE EQUILIBRIA IN THE Bi-In-Sn-Zn SYSTEM. THERMAL ANALYSIS VS. CALCULATIONSWith the use of the differential thermal analysis (DTA), studies of the phase transitions were conducted for 90 of alloys from the quaternary Bi-In-Sn-Zn system and for the constant ratio of Bi:In and Bi:Sn. The studies were conducted for the alloys prepared from the purity metals (Bi, In, Sn, Zn = 99.999 mas. %) by way of melting in a graphite crucible in a glove-box filled with Ar, in which the impurities level was less than 0.1 ppm. After melting and thorough mixing, the liquid alloys were poured out into a graphite test mold. The phase transition temperature data obtained from the DTA investigations were next confronted with those determined from the calculations based on the binary and ternary optimized thermodynamic parameters available in the literature. It was found that the experimental and the calculated phase transition temperatures were in good agreement.
