【摘要】 利用电子显微镜旋转晶体法发现了非晶Ni-P合金晶化过程中生成的另外两个新的六角亚稳相（α₂相与α₃相）。它们与文献[3]报道的六角亚稳相（α₁）具有相同的α值（6.73）,但c值分别为α₁的3/2倍与4倍,表明这些相属于长周期多型体结构,α₂相具有六角密堆结构的消光规律。此外,还证实了α₁中的面心立方亚点阵（α=5.50）实际上是一个单独的面心立方亚稳相,这些六角亚稳相就是在它的{111}面上生成的。更多还原

【Abstract】 By tilting the crystals formed in an amorphous Ni-P alloy during crystallization in transmission electron microscope, two further hexagonal metastable phases (a2 and a3) have been discovered. Their lattice parameter a has the same value (6.73 A) as that of the previously reported hexagonal metastable phase (a1), but the values of the other lattice parameter c are 3/2 and 4 times respectively of that of the phase a1. This shows that these phases are longperiod polytype structures. Furthermore, the previously assumed F.C.C. sublattice (a=5.50 A) of a1 has been found to be really metastable phase from {111} planes of which these hexagonal metastable phases are formed.更多还原
