Dynamic properties of bulk metallic glass on the base of Zr

Abstract

The high-strain-rate method of materials for dynamic strength investigations under microand sub-microsecond durations of shock loads on the base of electrical explosion of conductors was developed. The experimental investigations of dynamic properties for bulk metallic glass on the base of Zr under shock loads of sub-microsecond duration (∼0.5-0.7 μs) in the pressure range up to 12 GPa were carried out. The values of Hugoniot elastic limit (HEL) and spall strength for this amorphous alloy were received. The Hugoniot shock adiabat parameters were determined in the space U sh - u p. The result of microstructure analysis of saved specimens revealed areas of recrystallization. © 2012 American Institute of Physics.
