摘要
研究了非晶合金Fe73 .5Cu1Nb3Si13 .5B9(FINEMET)的激波晶化。与退火晶化比较 ,激波晶化具有一系列鲜明特征 ,这些特征是固态下扩散性相变理论难以解释的 ,有深刻的物理内涵。
Shock-wave and annealing cr ystallizations of alloy FINEMET were studied using XRD,DSC and TEM.It was found that amorphous FINEMET samples transformed into nanocrystals with grain size o f 30～50nm under shock loading. Comparing with annealing crystallization,many cha racteristics in the shock wave crystallization can not be explained using diffus ion theory.The shock wave nanocrystallization of amorphous alloy contains plentiful physical connotation.
