abstract = {This study explores both experimental and computational
aspects of the thermophysical properties of the novel
ternary BMG-forming Pd-Ni-S system. Unlike more complex
quinary BMG-formers, this ternary system's simplicity allows
for applying the CALPHAD approach to model the underlying
thermodynamics governing glass formation.Experimental
investigations include quantifying specific heat capacity
and studying crystallization across various compositions
critical for generating essential input data. Using a
two-state approach, initial modeling of the undercooled
liquid and glass is conducted for individual elements and
extended to the ternary system. Model predictions are
validated against experimental findings and iteratively
optimized. Using the parallel tangent method, the Gibbs free
energy of crystalline and liquid phases at different
compositions are calculated, providing a more accurate
estimation of the nucleation driving force of the first
forming phase compared to the conventional thermodynamic
approach. These calculated driving forces are then used to
model the isothermal Time-Temperature-Transformation (TTT)
diagrams, and finally for the estimation of the interfacial
energy between liquid and crystal during primary
crystallization, which plays an important role in the
glass-forming ability of this system. The experimental and
calculated results are found to be compatible for
near-eutectic compositions.},
