Isoperibolic calorimetry is used to specify the partial and integral mixing enthalpies of liquid Al–Ti(Zr, Hf) alloys at 1770 ± 5 K and 1790 ± 5 K. The concentration dependences of the mixing enthalpies of Al–Hf alloys are determined for the first time for 0 < x Hf < 0.2 at 1790 ± 5 K and relevant quantities are modeled for the entire concentration range. The data show that the mixing enthalpies of Al–Ti melts depend on temperature. The values of ΔS and ΔG are calculated for Al–IVb metal melts.
