【摘要】 研究了Ｂ２型金属间化合物ＦｅＡｌ和ＦｅＴｉ的机械合金化过程发现在相同的试验条件下，ＦｅＡｌ形成化学无序的固溶体，ＦｅＴｉ形成结构无序的非晶态。此现象可用ＦｅＡｌ的化学键为金属—离子混合键，而ＦｅＴｉ的化学键为金属—共价—离子混合键来解释。更多还原

【Abstract】 In this paper, the mechanical alloying process of two intermetallic compounds of the type B2 FeAl and FeTi has been investigated.It is found that FeAl forms a chemical-disordered solution, but FeTi exists in a structural-disordered noncrystalline state under the same experimental conditions. Such results can be explained by that FeAl is of the metallic-ionic mixed bonding and FeTi the metallic-covalent-ionic mixed one.更多还原
