Thermodynamic assessment of the Ag–Yb system

Thermodynamic assessments of the Ag–Tb and Ag–Ho systems

“…The calculated minimum values in the Ag-Tb and Ag-Ho systems are respectively −25.08 kJ/mol at 43 at.% Tb and −30.17 kJ/mol at 42.5 at.% Ho, which are close to the value (−29 kJ/mol) predicated by Boer and Perrifor [12]. It is seen that the minimum values of enthalpies of mixing of the liquid phase appear at about 40 at.% X in the Ag-X (X: Sc [22], Y [23], Ce [24], Nd [25], Gd [25] and Yb [26]) binary systems.…”

“…Calculated enthalpies of mixing of liquid phase with reference states of pure elements of Ag (liquid) and X (liquid)[22][23][24][25][26].…”

Thermodynamic assessments of the Ag–Er and Er–Y systems

“…at 43 at.% Er) is close to the value (−29 kJ/mol) predicated by Boer and Perrifor [10]. It is seen that the minimum values of enthalpies of mixing of liquid phase appear at about 40 at.% RE in the Ag-RE (RE: Sc [19], Y [20], Ce [21], Nd [22], Gd [22] and Yb [23]) binary systems. Therefore, the calculated enthalpies of mixing of liquid phase in the Ag-Er systems are reasonable.…”

Thermodynamic assessments of Ag–Dy and Ag–Er binary systems

“…Information of phase diagrams of the Ag-RE systems is helpful to alloys design relevant processing method. Recently, many assessments about Ag-RE systems have been carried out, including Ag-La [3], Ag-Pr [4], Ag-Ce [5], Ag-Gd [6,7], Ag-Nd [7,8], Ag-Yb [9], Ag-Eu [10], Ag-Y [11], Ag-Sc [12], Ag-Sm [13], Ag-Tb and Ag-Ho [14]. However, the Ag-Dy and Ag-Er systems have not been optimized despite their importance.…”
