| 摘 要： | 高压下与Al发生扩散反应的非晶(Fe0.99Mo0.01)78Si9B13（FMSB）的晶化产物与纯FMSB的不同。与Al反应的FMSB非晶在3.0~5.0 GPa、780~900 K热处理时，晶化为α-Fe(Al)和次亚稳非晶合金；在这一压力范围以外，720~900 K热处理时，晶化为α-Fe(Si)、Fe3B或Fe2B。与Al发生反应的FMSB非晶可能通过与Al的扩散反应在Al/FMSB界面开始晶化。压力和温度对晶化过程的影响主要是由于α-Fe固溶体的Gibbs自由能随压力、温度和Al含量的变化。

| Abstract: | Crystallization products of amorphous (Fe0.99Mo0.01)78Si9B13 (FMSB) alloy or pure amorphous FMSB alloy reacted with Al are different under high pressure. The amorphous FMSB alloy reacted with Al may start crystallization at Al/FMSB interface by reacting diffusely with Al. It crystallizes to α-Fe (Al) and second-amorphous phase in the range from 3.0 to 5.0 GPa in the temperature range of 780 K to 900 K and to α-Fe (Si), Fe3B or Fe2B beyond the range of 3.0 to 5.0 GPa between temperatures of 720 and 900 K. The effect of pressure and temperature on its crystallization process comes mainly from the change of Gibbs energy of α-Fe solid solution with pressure, temperature and Al content. |
