摘要

摘要: 研究了非晶(Fe0.99Mo0.01)78Si9B13（FMSB）合金的机械晶化过程和机制，并讨论了局域高压的作用。结果表明：非晶FMSB合金的晶化过程及其产物与球磨强度和球磨时间有密切关系，在低能球磨FMSB非晶过程中，晶化相只有-Fe(Mo,Si)固溶体，而在高能球磨过程中，除了-Fe(Mo,Si)固溶体结晶相之外，还分别有(Fe,Mo)3B和Fe2B相析出。其晶化机制可归因于由碰撞引起的局域高压和局域高温共同作用的结果。实验结果还表明，机械球磨不仅对非晶FMSB的常压热晶化温度有重要影响，而且对其热晶化结果亦有重要影响。

Abstract: Crystallization processes and mechanism of amorphous (Fe0.99Mo0.01)78Si9B13 (FMSB) alloy induced by mechanical milling were studied. We suggested that local high pressure has influence on mechanical crystallization, and discussed the effect of local high pressure on amorphous crystallization. It was found that crystallization processes and its products of amorphous FMSB alloy were related closely to milling intensity and time. Only a crystallization product, -Fe(Mo,Si) solid solution occurs in the case of lower milling intensity, however, Fe3B and Fe2B phases appear besides the -Fe(Mo,Si) solid solution in the case of higher milling intensity. We suggested that the crystallization mechanism is the co-interaction due to local high pressure and temperature induced by ball collisions. It is also found that mechanical milling has an important influence on both thermal crystallization temperature under normal pressure of amorphous FMSB and thermal crystallization results.
