【Abstract】 Both shock wave crystallization and annealing crystallization of amorphous alloys FeSiB, FeMoSiB and FeCuNbSiB were studied by x-ray diffraction, transmission electron microscopy,and differential scanning calorimetry techniques. A series of novel physical effects of shock wave crystallization have be found according to the experimental results. These physical effects are very difficult to explain by the diffusion theory of solid-state phase transition, but using the theory of fluid diffusion change for shock wave crystallization is feasible.更多还原
