Abstract
Dynamic compaction of amorphous Fe80P16C4 powder produced by rapid quenching water atomization process was performed using by a gun accelerator. The effect of shock duration time on the magnetic properties has been investigated by means of X-ray diffraction analysis, microhardness test, optical microscopy, scanning electron microscopy and magnetic measurements. The results indicate that the magnetic properties of dynamically compacted amorphous powder are highly affected by shock duration time, and can be described by a change in the atomic short-range order which is caused by shock pressure and temperature.
