Ti12.5Zr21V10Cr8.5MnxCo1.5Ni46.5−x AB2-type metal hydride alloys for electrochemical storage application: Part 1. Structural characteristics

► The secondary phases in AB2-type MH alloy were studied by SEM, TEM, EBD, and EBSD. ► The solidification sequence of these secondary phases was identified. ► The composition and abundance of the final B2 phase were varied and analyzed.
