摘要
本文研究了微量合金元素硼在体心立方结构金属间化合物Fe_3(SiAl)中的分布对长程有序度的影响及其对脆性的改善。提出了一种硼改善体心立方结构金属间化合物脆性的新机制,即晶内弱化机制。
Studies were made of the influence of B distribution in bcc lattice in-
termetallic compound Fe_3(Si, Al) on the long range order and the improvement on
its brittleness. A new mechanism concerning weakening of grain interiors is put for-
ward. Based on this mechanism, the brittleness improvement of the bcc intermetallics
with B addition could be well explained.
