Refractory Metals › Penetrators
|
The current use of depleted uranium alloys are used for kinetic energy armor penetrators raises a number of environmental and health issues. There is currently no substitute material which has the armor penetration performance of depleted uranium alloys. Research under Army sponsorship has shown that the performance of current commercial liquid phase sintered tungsten composite cannot be significantly improved by incremental process or alloy modifications. Novel materials have been investigated including hafnium alloy matrices.
