具有表面扩散反应的非晶FMSB晶化热力学机制研究

Study on Thermodynamic Mechanism Amorphous FMSB with Surface Diffusi

研究了在大气压力为３×１０３～５×１０３ＭＰａ、温度为７８３～９０３Ｋ时，表面具有与Ａｌ发生扩散反应的非晶（Ｆｅ０．９９，Ｍｏ０．０１）７８Ｓｉ９Ｂ１３即ＦＭＳＢ合金的晶化过程，给出了α－Ｆｅ（Ａｌ）和α－Ｆｅ（Ｍｏ。

The crystallization of amorphous (Fe 0 99 ,Mo 0 01 )78Si 9B 13 (FMSB)alloy which having diffusion reaction with metal Al at their surface has been studied under a pressure of 3×10 3～5×10 3MPa and at a temperature of 783～933 K.The change of the Gibbs′ free energy of α Fe(Al) and α Fe(Mo,Si) with pressure is given,and the crystallization of FMSB is suggested.
