Abstract
Studying the Ni-Si system, we confirmed the only known Ni31Si12 (S12) structure and in addition several new gamma modifications were also observed. Our TEM/STEM studies of gamma Ni-silicides revealed crystal structures with different atomic arrangements and even varying c cell parameters (∼6 Å, ∼12 Å, ∼18 Å, ∼36 Å). Three of them were determined and named S6a, S6b and S18. The nomenclature of S6, S12 and S18 refers to their c cell parameters which are multiples of ∼6 Å. Nanoscale variability was also observed in the gamma Ni-silicides, where nanoscale variability was the outcome of stacking, inversion, twinning and intimate (001) intergrowths of the different modifications.
