文摘
- •
Two experimental peaks were observed in DSC of (Fe0.5Co0.5)73.5–xNixSi13.5B9Nb3Cu alloy.
- •
Best thermal stability and maximum Ea value were gained at 4 at.% addition of Ni.
- •
Apparent activation energy was calculated by using the Kissinger and Ozawa models.
- •
JMA (n) model was used to analyze the nucleation and growth mechanism.
