Dynamic properties of a magnetic alloy Fe-Cr-Co

The high-strain-rate methods of materials were developed for dynamic strength investigations under microsecond durations of shock loads on the base of electrical explosion of conductors. The experimental investigations of dynamic properties for magnetic alloy Fe-Cr-Co under shock loads of microsecond duration (4-8) mks in the pressure range up to 20 GPa were carried out. The values of HEL and spall strength for these amorphous alloys were received. The results of microstructure analysis of saved specimens revealed essential differences in deformation mechanisms determining fracture and plasticity in these alloys under high-strain-rate.
