The Role of Transition Metals in Crystallization of Amorphous Al–Ni–Co–Yb Alloys

Al₈₆Ni₄Co₄Yb₆ and Al₈₆Ni₆Co₂Yb₆ metallic ribbons have been obtained by a standard planar flow method. According to X-ray diffraction data, the ribbons are amorphous. Their crystallization kinetics at different heating rates and resistivity has been determined. These alloys remain amorphous in a wide range of compositions, and the crystallization process depends significantly on transition metal concentration.
