The excellent mechanical properties, magnetic properties, corrosion resistance properties, electrical properties, and applications of Fe-based bulk amorphous alloys are summarized. The latest achievements in the crystallization and crystallization kinetics of Fe-based bulk amorphous alloys are introduced, including the influence of crystallization on the properties of amorphous alloys and the method of calculating crystallization activation energy in non-isothermal transition. Meanwhile, a new non-isothermal method for evaluating the crystallization kinetics of metallic glasses is found, i.e., Starink method. It is best to use the Starink equation to calculate crystallization activation energy, Kissinger equation is the second, Boswell equation is the third, and Ozawa equation is the worst.
