Crystallization Behavior and Resistivity of Al–Ni–Co–Nd(Sm) Amorphous Alloys

— Aluminum-based metallic ribbons with the compositions Al 86 Ni 4 Co 4 Nd(Sm) 6 and Al 86 Ni 6 Co 2 Nd(Sm) 6 were produced by melt spinning.

Description
Summary:— Aluminum-based metallic ribbons with the compositions Al 86 Ni 4 Co 4 Nd(Sm) 6 and Al 86 Ni 6 Co 2 Nd(Sm) 6 were produced by melt spinning. X-ray diffraction characterization showed that the ribbons had an amorphous structure. Their crystallization kinetics were studied by differential scanning calorimetry and their resistivity was measured by a standard four probe method. The Al–Ni–Co–REM ribbons were shown to have a broader temperature range of an amorphous state than do Al–Ni(Co)–REM ternary alloys. We found compositions with an enhanced glass-forming ability.
