材料科学技术(英文)

The giant stress-impedance (GSI) effect in amorphous and current annealed Fe73.5Cu1Nb3Si13.5B9 ribbons has been investigated. The results showed that the GSI effect changed drastically with annealing techniques and the maximum stress impedance ratio of 350% was obtained after optimal conditions of c...

Electrochemical behavior of Mg, Li and Sn on tungsten electrodes in LiCl-KCl-MgCl2-SnCl2 melts at 873 K was investigated. Cyclic voltammograms (CVs) showed that the underpotential deposition (UPD) of magnesium on pre--deposited tin leads to the formation of a Mg-Sn alloy, and t...

Giant magneto-impedance effect in Fe96-xZrxB4 (x=7 or 10) nanocrystalline ribbons

Zhichao LU , Wei HAN , Deren LI

材料科学技术(英文)

The total ribbon voltage of as-quenched and annealed Fe96-xZrxB4 (x=7 or 10) ribbons has been measured as a function of applied de field and drive current frequency. The experimental results show that both samples exist the optimum annealing temperature and optimum frequency at which the relative ch...
