| 摘 要： | The disaccommodation(DA)measurements of initial susceptibility were performed inamorphous Fe_(90-x)Ni_xZr_(10)(x=10,20,30)alloys.The DA was measured for two differentamorphous states:as-quenched and pretreated at 537 K for 45 min.For all the as-quenched samples,in the isochronal spectra of DA a well defined relaxation peak around350 K is accompanied by a samll but distinct peak near the Curie temperature ofFe_(90)Zr_(10) phase(T_c=230 K).The reversibility and annealing effect on DA are analyzedwithin the framework of two-level model.The fits of the theory to the experimentaldata of reversible relaxation processes gave a spectrum,of activation energies and pre-exponential factor.

| Abstract: | The disaccommodation(DA)measurements of initial susceptibility were performed in amorphous Fe_(90-x)Ni_xZr_(10)(x=10,20,30)alloys.The DA was measured for two different amorphous states:as-quenched and pretreated at 537 K for 45 min.For all the as- quenched samples,in the isochronal spectra of DA a well defined relaxation peak around 350 K is accompanied by a samll but distinct peak near the Curie temperature of Fe_(90)Zr_(10) phase(T_c=230 K).The reversibility and annealing effect on DA are analyzed within the framework of two-level model.The fits of the theory to the experimental data of reversible relaxation processes gave a spectrum,of activation energies and pre- exponential factor. |
