Thermodynamics of liquid Al–Sn–Zn alloys and concerned binaries in the light of soldering characteristics

Atomic order and interionic pair potentials in Cu–Sn liquid alloys

“…(7)) contains n 1 , n 2 , n 3 , n and interaction energy parameters (g, V 13 , V 23 and V 12 ). n 1 , n 2 and n in Eq.…”

“…The computed pair potentials have been minimized [8,12] to obtain the hard sphere diameter of the component elements of the alloy. Besides, the concentration dependent thermodynamic and microscopic properties [3,[13][14][15] are greatly affected by the formation of intermetallic compounds in the melt. Without understanding the cause of anomaly in these properties, one cannot get the real picture of the mixing behaviour in such alloys.…”

Thermodynamic properties of Al in ternary lead-free solder Al-Sn-Zn alloys

“…Also, in Table 3, the average relative error, S i and standard error, S i * were respectively computed using the equations [37]: in Table 3 for the three cross-sections with mole ratios of other two components maintained as 2:1, 1:1 and 1:2 at a temperature of 973 K alongside with the concentrations of Sn and Zn, respectively. This is coupled with the fact that the alloy is considered an important lead-free soldering material for industrial application [23]. Similarly, using the parameters V mi , A ji , A ij , Z i and Z j provided in Table 1 and Table 2, The predictions were made in the ternary systems at each of the three different cross-sections with constant molar ratios of the other two components remaining as 2:1, 1:1 and 1:2, respectively.…”

“…Thus, Al-Sn-Zn system is worth thorough investigation. Nonetheless, the binary constituents of Al-Sn-Zn system have been investigated, for instance Al-Zn [17][18][19][20][21], Sn-Zn [22][23][24] and Al-Sn [9,25]. Extensive experimental studies of the ternary phase diagrams of the Al-Sn-Zn systems have been already reported [26,27].…”

Analytic Approach to Alloys Thermodynamics: Ternary Cu-Ga-Ni system

“…Among available models, general solution model developed by Chou 3,4 has been proved to be most reasonable one in all aspects. This geometric model has been successfully used by different researchers for calculation of thermodynamic properties [6][7][8][9][10] , construction and/or evaluation of phase diagrams [11][12][13] , computing physicochemical properties [14][15][16] and solving technical problems [17][18][19][20] . In 2010 Zhang and Chou 5 published new, improved version of general solution model for calculation of thermodynamic properties of liquid mixtures, based on binary Redlich-Kister type parameters and this version has been used to predict thermodynamic properties of metallic systems in liquid phase 21 .…”
