    Abstract
  • Shock wave and annealing crystallization of amorphous alloys FeSiB, FeMoSiB and FeCuNbSiB were investigated by isothermal and non-isothermal DSC technique. It is found that shock wave crystallization is very perfect (fraction crystallized is very close to 100%) though the period of crystallization is very short, only about 10-6～10-8 of annealing's. Produced phases are different from the parent phase in structure and composition, shock wave crystallization is similar to the diffusion solid state phase transition in form, however, it is very difficult to explain the high velocity of transformation by the diffusion theory of solid state phase transition. Shock wave crystallization of amorphous alloy is a new method.
