| Abstract: | Shock-wave and annealing crystallizations of alloy FINEMET were studied using XRD, DSC and TEM. It was found that amorphous FINEMET samples transformed into nanocrystals with grain size of 30～50 nm under shock loading. Comparing with annealing crystallization, many characteristics in the shock wave crystallization can not be explained using diffusion theory. The shock wave nanocrystallization of amorphous alloy contains plentiful physical connotation. |
