Abstract

The critical cooling rate of the Fe₆₁Co₅Zr ₈Y₂Cr₂Mo₇B₁₅ bulk amorphous alloy was determined to be 37 K/s, providing an indication that this alloy has a high glass-forming ability. The non-isothermal crystallization kinetics of the Fe₆₁Co₅Zr₈Y₂Cr ₂Mo₇B₁₅ amorphous alloy prepared by using the copper-mold casting or melt-spinning were also investigated. It is found that the activation energies in the non-isothermal crystallization process show a strong dependence on the cooling rates for glass formation, revealing that the melt-spun amorphous alloy has a higher thermal stability.
