Binary Eutectic Mixture & Melting Point Depression Calculator
Calculate binary alloy eutectic melting temperature, liquidus phase depression, and eutectic composition from thermodynamic fusion enthalpy and pure component melting points.
Estimated Eutectic Melting Point
Calculator Inputs
Estimated Eutectic Melting Point
Max Melting Point Depression
Lower Component MP
Deep Eutectic Melting Point: Alloy transitions to liquid well below both pure constituent temperatures, optimizing low-thermal soldering and casting.
Pure Components vs Eutectic Melting Point
Standard materials science and chemical thermodynamics tool for binary solid-liquid phase diagrams.
Calculation Methodology
Schröder-van Laar Ideal Liquidus Equation: ln(X) = (ΔH_fus / R) * [ (1 / T_m) - (1 / T) ]. The eutectic point marks the simultaneous crystallization of both components at the lowest invariant liquidus temperature (T_eutectic < T_A and T_B).
