Their kinetics of crystallization was studied by X-rays, DSC and electric resistivity. Al – (Ni + Co) – REM metallic glasses are characterized by the wider (for 100 K) interval of amorphous state in comparison with Al-Ni-REM and Al-Co-REM alloys. They have higher values of electric resistivity and their crystallization goes in more complicated way. The alloy with Gd demonstrates wider and more stable interval of amorphous state in comparison with Tb-containing alloys, and the combination (4% Ni + 4% Co) is preferable than (6% Ni + 2% Co).
