THE INTERNAL FRICTION STUDY OF THE INTERFACE DYNAMICS IN AMORPHOUS Fe40Ni40P10B10 ALLOY DURING THE PROCESS OF ATHERMAL CRYSTALLIZATION TRANSFORMATION

The Internal friction (IF, Q-1), shear modulus (M, f 2), resistivity (Ɗρ) and DSC curves of amorphous Fe40Ni40P10B10 (a-FeNiPB) alloy were measured in the process of crystallization . An explicit functional relation between the average velocity V of amorphous/crystalline interface and the difference of driving force ƊG and resistance ƊGR, ƊG' = ƊG-ƊGR, was derived as V=ϕ(ƊG-ƊGR) during the process of athermal crystallization transformtion of a-FeNiPB
