Preliminary Study of Alternative Material Development of ballistic Attributes

摘要

The purpose of this research is to examine the performance of tungsten heavy alloy (WHA) susceptible to adiabatic shear failures and to identify the microscopic findings of shear band and its effect on the engineering behavior. Experimental results show that the binder-phase (Fe-Ni) and tungsten particles (W) have the high work-hardening rate at low-strain-rate compresion (10~-3 /sec). Thermal softening behavioris dominant at high-strain-rate (> 10~3 /sec), and this material is relatively insensitive to strain rate in the range of 3000 - 5--- /sec.
