| 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α-Fe基固溶体，次晶化相为Fe3Si，且观察到α-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 μs and that the first crystallized phase is solid solution of α-Fe and the second phase is Fe3Si. Besides, the lattice constant of α-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. |
