A new kind of GMI magnetic sensor based on giant magneto-impedance effect of Fe-based alloy thin ribbon and characteristics of LC resonant circuit was developed.

Fe-based alloy droplets were generated by Uniform Droplet Spray(UDS).

A new technics of crystallization of Fe-based alloy(Fe_(73.

To improve the microstructure and wear resistance of plasma clad Fe-based alloy coating, a mechanical vibration technique was applied into plasma cladding process.

Since ferroalloy is liable to corrosion in melting zinc,it is imperative to evaluate the anticorrosion behavior of the ferroalloy fast and accurately in terms of the selection of the ferroalloy materials.

A research on using the digital analysis system to analyze the vanadium element of ferroalloys was conducted including to record the visible spectrum of the vanadium,to observe and analyze its spectrum and so on.

The change of the 3d shell electrons of Fe-based alloys at high pressure and temperature has been measured by using electron energy spectra and Mossbauer spectra,which reveab the bond reaction between the unpaired electrons in the 3d shell of Fe atoms and the 2Px electrons of carbon atoms in synthetic diamond.
