【摘要】 利用电镜双倾台倾转Ni₁₂P₅晶体以及对Vafaei-Makhsoos发表的数据的分析,证实了由他所提出的三个新的Ni₃P相并不存在。从而澄清了非晶Ni-P合金在加热过程中总共有七个晶化相析出:a=5.48的面心立方亚稳相α,由此相转变生成的六角多型体α₁,α₂,α₃亚稳相,体心四方Ni₁₂P₅相,体心四方Ni₃P相及Ni固溶体。更多还原

【Abstract】 Vafaei-Makhsoos claimed to have discovered three new Ni3P phases in crystallized Ni-P amorphous alloy. By analysis of his experimental data as well as our own electron diffraction experiments, it is shown that the various electron diffraction patterns of the so-called new Ni3P phases are in fact all belonging to Ni12P5. Thus it is clear that there are seven crystallization phases in annealed amorphous Ni-P alloys: metastable fcc phase α (α=5.48 A), metastable hexagonal polytypes α1, α2, α3 transformed from α, bct Ni12P5, bct Ni3P and Ni solid solution.更多还原
