On the basis of the analysis of the results of the study of the formation of quenched metal melts of short-range, intermediate order in amorphous and long-range order in nanocrystalline alloys, it was shown that in both obtained states the structure in the groups of metal atoms is realized not only by icosahedral packings but also helicoidal, combining due to fractional symmetry, coherent crystalline and non-crystalline coordination.
