THERMAL PROPERTIES OF NANOCRYSTALLINE Fe_(78)B_(13)Si_9 ALLOY
Fe78B13Si9纳米晶合金的热性能研究

A method was developed for preparing nanocrystalline alloy made of the iden- tical compositional Fe_(78)B_(13)Si_9 amorphous ribbon by suitable isothermal annealing. Its microstructure and some structure-sensitive properties, including thermal expansion, specific heat, etc., have been studied and measured. Comparative analysis of properties was also car- ried out with amorphous and coarse-grained crystalline alloys of 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 nanocrystalline alloy.
