Compared with the well known annealing crystallization, these results seem novel and are very difficult to be explained by the diffusion theory, such as nucleation and growth mechanism in the solid state phase transitions. The shock wave crystallization of amorphous alloy is a new metallurgical phenomenon with possibilities for improving the crystallization theory in physics.展开更多

It was found that the shock wave crystallization is very perfect, the fraction crystallized is very close to 100%, though the period of crystallization is very short, only about 10-4-10-6s. Their produced phases differ from the parent phase in structure and composition. The high velocity of the transformation is very difficult to explain by the diffusion theory of solid state phase transition.展开更多
