摘要

The present invention be a second level by dispersal oxide particle by a mechanical alloying process improve oxide dispersion elongation reinforce tungsten be related to a manufacturing method, tungsten powder and oxide powder are mechanically fused in a first step by first, with a transition step of the mechanical alloying of a second level or mechanical alloying metal powder that are mixed in step 1 described above to the alloy powder obtained in step 2, it is characterised in that pass through. Since phenomenon is best shown, according to the present invention, from when maintaining same intensity, compared with prior art, since tungsten improves elongation, oxide quantity can have been increased, self is consumed and (be prone in self shearing strain of failure, improvement with the calorific intensity that result is sharpened), it is suitble to the characteristic kinetic energy shooting with excellent acumen to be used together penetrable material and represents version.
