Abstract: Shock wave and annealing crystallization of amorphous alloys FeSiB, FeMoSiB andFeCuNbSiB were studied by isothermal and non-isothermal DSC technique. It wasfound that the shock wave crystallization is very perfect, the fraction crystallized isvery close to 100%, though the period of crystallization is very short, only about10-4-10-6 s. Their produced phases differ from the parent phase in structure andcomposition. The high velocity of the transformation is very difficult to explain by thediffusion theory of solid state phase transition.
