The Al-V phase diagram was reviewed by [2001Oka]. Further investigation was needed because the phase diagram assessed by [1989Mur] disagreed significantly with the experimental result reported later by [2000Ric]. For example, the peritectic melting point of Al8V5 estimated at 1670 C by [1989Mur] must be 1408 C [2000Ric]. Figure 1 shows the Al-V phase diagram assessed by [2004Gon] by taking into account the result of [2000Ric]. The Al-V phase diagram was calculated earlier by [1987Kau] based on old data. [2006Kos] also calculated the phase diagram, but the data of [2000Ric] were overlooked. The AlV3 phase has not been discussed in all thermodynamic models described above. In order to attract attention, boundaries of the AlV3 phase has been copied from [1989Mur] in Fig. 1. References
