1) W atom site occupation
W原子占位
2) site occupation
原子占位
1.
The site occupation of substitutional atoms Cr, Mo, Ti, Ni, Mn, Si at sublattice in DO3 type stoichiometric Fe3Al intermetallics has been determined by means of neutron difractometry.
采用中子衍射法测定了Cr,Mo,Ti,Ni,Mn,Si等代位原子在DO3结构Fe3Al亚点阵中的原子占位,并从解离能角度探讨了原子对之间的相互作用及对合金室温塑性的影响、结果表明:Cr,Mo,Ti都占据Al原子的次近邻位置,替代Fe原子;Ni,Mn占据Al原子的最近邻位置;(Si+Al)当量成分以内的Si原子替代占据Al原子的位置。
2.
