Dispersion-
strengthened copper (DSC) with WC as dispersoid was prepared by means of mechanical alloying
(MA) following
the tradinonal powder metallurgy (P/M) route. Influence of WC content on the propertes of material was
discussed in detail, and result shows that when the volume fraction of WC is 1.6%, the material achieves the best overall
property, and a little more particle addition led to a less superior property owing to occurrence of particle agglomeration.
The as-sintered composite was designed to undergo a
deformation of 75%. It is proved that appropriate deformation is
helpful to attain a higher density and consequentiy better properties. Deformed material was then exposed to elevated tem-
perature to test its effect on material. Annealing for 1 h at 1173K caused material to reeover quite completely, but no obvi-
ous recrystallization was observed. It's supposed the particles handicaps motion of dislocations and material demonstrates
good retention of strength with substantial improvement in elongation.
