摘　　要：应用x射线衍射、透射电子显微镜和差示扫描量热实验技术 ,研究了FeCuNbBSi,FeBSi,FeMoBSi几种铁基非晶合金的激波诱导晶化 .研究结果表明 :非晶态合金激波诱导晶化中存在若干应用传统长程扩散相变理论难以解释的奇异物理效应 .用非晶态合金激波流化晶化可以很好地解释激波诱导非晶晶化中的各种奇异物理效应 .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.
