A new method was developed for preparing nanocrystalline alloy made of the identi-cal compositional Fe_(78)B_(13)Si_9 amorphous ribbon by suitable isothermal annealing.Itsmicrostructure and some structure-sensitive properties.including thermal expansion,spe-cific heat,etc.,have been studied and measured.Comparative analysis of properties wasalso carried out with amorphous and coarse-grained crystalline alloys of same composi-tion,thus.it is believed that so novel differences in properties from usual materials wouldbe made by the particular microstructure of short range disorder of the nanocrystallinealloy.

Comparative analysis of properties was done with amorphous and coarse-grained crystalline alloys of the same composition, thus .it is believed that so novel differences in properties from usual materials would be made by the particular microstructure of short range disorder of the nanocrystallinealloy.
