Thermodynamic properties of liquid alloys of 3d transition metals with metalloids (silicon, carbon and boron)

Thermodynamic Properties of Metal-Carbon Melts

“…Our results on the thermochemical properties of Ni − C melts agree to within the experimental error with the data reported by Witusiewicz [6]. In Ni-C melts with 0 < x C < 0.08, the interaction between dissimilar atoms prevails.…”

“…The standard enthalpies of formation of iron-group carbides were reported in [9,10] to be positive, which is at variance with the experimentally determined enthalpies of mixing of Fe-C, Co-C, and Ni-C melts [6]. The point is that, at atmospheric pressure, the iron-group carbides either are metastable or exist only at relatively low temperatures.…”

Thermodynamics of formation of aluminum–iron–germanium amorphous alloys

“…Although the model is approximate one, its forecasting is in a good agreement with many of experimental results [23,27]. Physically GFT is a magnitude, which shows as far as the alloy can transform into amorphous state easier than chosen pure component (in present calculation this component is aluminum).…”

“…The alloy of selected composition forms metallic glass readily, if GFT value is more then zero. The formula applied earlier in [23] for ternary alloys was used with some corrections. For ternary Al-Fe-Ge alloys, in the case, when the melt contains binary Fe m Ge n clusters and D mix H ðx Al Þ data set was defined for concentration sections with constant x Ge :x Fe relation, the equation for GFT should be as…”

“…The temperature of glass-forming was taken to be 500 K in accordance with [23]. Integral entropy and Gibbs free energy of mixing were calculated from respective excess thermodynamic functions of mixing:…”
