“…Based on AMCT [15][16][17][18] and Mg-Zn phase diagram, six kinds of structural units, Mg, Zn, MgZn 2 , Mg 2 Zn 11 , Mg 4 Zn 7 and MgZn, can coexist in molten Mg-Zn system. As the similar regressing process of Mg-Al [16,17] and Al-Ti [15,18], the primary regression of at four studied temperatures can be obtained with the measured activities of Mg and Zn from the references [8][9][10][11]23] and substituted into Eq. (13).…”

“…Balanović et al [11] measured and calculated the activity of Al and Zn at 1000 K, and Wasiur et al [23] summarized the activities of Al-Zn at 1073 K, showing that both Al and Zn have a positive deviation with Raoult's law. Zhang et al [16] argued that this kind of melts can be defined as the heterogeneous system and introduced the calculation process.…”

“…Since the various applications of Mg-Al-Zn, previous researchers had directed tremendous attention to the Mg-Al-Zn system, especially to the thermodynamic behavior of the molten system. During the investigation of thermodynamic properties in liquid Mg-Al-Zn ternary system including Mg-Al [3][4][5][6], Mg-Zn [8][9][10] and Al-Zn [11][12][13] subsystems, some thermodynamic models and empirical formulas, listed in Table 1, were established and introduced to describe thermodynamic reaction abilities. Nevertheless, one of the potential problems for thermodynamic models is that the artificial parameters are employed in prediction formulas, triggering controversial results in the prediction models, so that the above mentioned prediction models may not work well.…”

A developed and verified thermodynamic model based on the atom and molecule coexistence theory (AMCT) is employed to predict activities relative to pure liquids in standard state in Mg-Al, Mg-Zn, Al-Zn and Mg-Al-Zn melts through the calculated mass action concentrations of structural units, i.e., N i. According to AMCT, N i can be extrapolated and calculated by the chemical equilibrium constant of a structural molecule, i.e., K i , in the Mg-Al-Zn ternary system and binary subsystems. In this paper, the standard Gibbs free energy function, for reported activities and mixing thermodynamic properties in Mg-Al, Mg-Zn and Al-Zn melts, was regressed and optimized. The results showed that K i and N i were deduced by Gibbs free energy function at the studied temperature. The results of calculating thermodynamic properties in the full composition range for liquid Mg-Al-Zn from 880 to 1100 K, as well as Mg-Al from 923 to 1073 K, Mg-Zn from 880 to 973 K and Al-Zn from 1000 to 1073 K, are presented in the paper by coupling with N i and AMCT. An excellent agreement is noticed between the calculated values of this study and measured thermodynamic data from the references, suggesting that the AMCT can be well applied to describe and predict the activities of the Mg-Al-Zn system and its subsystems.

“…Such a special class of materials are the shape memory alloys (SMA) that possess a range of desired properties, especially a high mechanical capacity in comparison with their weight, through which is developed the ability of recovery, a deformation produced by a massive transformation and a deformation due to heating and cooling, pseudo-elasticity (super elasticity), high capacity of damping, high chemical corrosion resistance, and bio-compatibility (in the case of alloys based on Ti and Fe) [4][5][6].…”

In-Situ Plasma Monitoring during the Pulsed Laser Deposition of Ni60Ti40 Thin Films

The properties of pulsed laser deposited of Ni60Ti40 shape memory thin films generated in various deposition conditions were investigated. In-situ plasma monitoring was implemented by means of space- and time-resolved optical emission spectroscopy, and ICCD fast camera imaging. Structural and chemical analyses were performed on the thin films using SEM, AFM, EDS, and XRD equipment. The deposition parameters influence on the chemical composition of the thin films was investigated. The peeled layer presented on DSC a solid-state transformation in a different transformation domain compared to the target properties. A fractal model was used to describe the dynamics of laser produced plasma through various non-differentiable functionalities. Through hydrodynamic type regimes, space-time homographic transformations were correlated with the global dynamics of the ablation plasmas. Spatial simultaneity of homographic transformation through a special SL(2R) invariance implies the description of plasma dynamics through Riccati type equations, establishing correlations with the optical emission spectroscopy measurements.
