The damping behavior of thermal martensite and deformed for Fe-Mn alloys as well as the effects of cold rolling deformation, heat treatment and the condition on the damping behavior of Fe-Mn based alloys have been investigated systematically by means of thermal mechanical analyzer (TMA), scanning electron microscopy (SEM) and X-RAY diffraction.

Electronic structure and magnetic property for ε-martensite in Fe-Mn alloy;

Antiferromagnetic Fe-Mn alloys are ideally required to have large magnetostriction coefficients,excellent mechanic processability and relatively low cost,which makes it a new kind of magnetostrictive material.

Fe-Mn alloys have been widely applied to industrial facilities because of their good mechanical properties,high damping capacity at great strain amplitude and low cost.

In order to train the students innovative and comprehensive application ability,by use of the existing instrument and equipment,the comprehensive experiment of preparing magnetic Fe-Co alloy materials by electrochemical technique was designed,which would be carried out in senior students of applied chemistry major.

In this study, we used process control agents (PCA) during MA process and investigated the effect of PCA on the characteristics of the Fe-Co alloy powder.

Advances in preparation study of nano magnetic material Fe-Co alloys;

Fe-Co alloys are important soft magnetic materials,and applied extensively.

The complex permittivity and permeability of composites made from Fe-Co alloys and hollow carbon fibers embedded in paraffin matrix separately are measured by voter network analyzer and the reflectivity is calculated within 2~18GHz.
