A comparison of experimental and Calphad analyses of the Aluminum-Bismuth-Gallium system

Thermodynamics and phase equilibria in the Al–Bi–Sb system

“…The calculated value for the parameter is therefore, found to be in agreement with the concept of the central atoms model. [13] 0 0 0 a 4 [13] 0 0 0…”

“…Similarly, the partials for the components 2 and 3 are obtained by using equations (3), (5) and (6) and expressed as ln Table 5 presents the literature values [13][14][15] pertaining to the constituent Al-Bi [13], Al-Sb [14] and Bi-Sb [15] binaries in the form of parameters a 1 to a 12 along with the evaluated values of a 13 , a 14 and a 15 parameters involved in equation (3). The computed values of ln c Al (equation (7)) in the alloys are listed along with those of the experimental data in table 6.…”

“…Since the literature data [13][14][15] pertaining to the constituent binaries of the system are, expressed in terms of Redlich-Kister polynomial, the latter values may be transformed to their corresponding 'a' parameters of equation (1) using the above relations. Equation (1) describes the properties of the 1-2 binary system.…”

“…It may be mentioned that the thermodynamic behaviour of many binary systems has recently been assessed through the Redlich-Kister polynomial and are available from several compilations [13][14][15]. The polynomial may be represented [12] as…”

Activities of Al in the Al+Ga+Bi+Sb system in the temperature range (1173 to 1323) K

“…The binary and ternary parameters involved in equation (6) are used from the available literature data [2,[6][7][8][9][10] and are listed in table 5. Table 6 …”
