摘要: 研究了Fe78B13Si9、(Fe0.99Mo0.01)78B13Si9非晶合金的激波晶化行为。激波是由氢-氧爆炸产生的。实验结果表明：激波能使非晶合金在微秒时间内晶化，晶化主相为-Fe基固溶体，次晶化相为Fe3Si，且观察到-Fe基因溶体晶格常数变小。用DTA分析进一步证实：激波晶化是比较完全的，晶化相相当稳定。Abstract: The shock wave-crystallizations of amorphous Fe78B13Si9 and (Fe0.99Mo0.01)78B13Si9 alloys are studied. The shock wave was produced in a H2 and O2 explosive shock wave tube. The experimental results suggest that the nano-crystallization of metallic glasses Fe78B13Si9 and (Fe0.99Mo0.01)78B13Si9 could be completed under shock wave within the time of the order of s and that the first crystallized phase is solid solution of -Fe and the second phase is Fe3Si. Besides, the lattice constant of -Fe solid solution is determined to be smaller than that of pure Fe. DTA analysis indicates that the shock wave-crystallization is very complete and the first crystallized phase is rather stable.
