Abstract (en)
Producing a penetrator from a tungsten/heavy metal alloy with a high tungsten content by compressing, sintering and optionally heat-treating a tungsten-containing powder mixture and cold-working the resulting blank comprises heating the surface layer of the blank to a temperature above the recrystallization temperature of the alloy so that the surface layer recrystallizes.
