Abstract

In a Mg-Sc system, a bcc (β) phase exists in a high-temperature region, and the quenched β shows drastic age-hardening and shape-memory properties. In addition to the disordered β phase, the ordered β (B2) phase is reported to exist in a low-temperature region. We report that the quenched β phase can be ordered through aging treatment at 573 K. This finding indicates that the mechanical characteristics and shape-memory functionality of β-type Mg-Sc alloys can be controlled by ordering the β phase.
