METHOD FOR PRODUCING COMPACT SUPERHARD MATERIAL

摘要

This invention pertains to the production of a compact superhard material from diamond and/or adamantine modifications of boron nitride, and provides compact superhard materials with high working properties. This method essentially comprises, before preliminary plastic deformation, adding, as a metallic linking agent to the superhard material powder, 3 - 90 vol.% of ultra-dispersive powder of a metal from the iron group with a particle size ranging between 100 and 1000 ANGSTROM . The final plastic deformation is obtained by a shock wave with a 1-25 GPa front amplitude and/or by plastic deformation at a temperature of 600 to 900 DEG C and with a deformation speed from 10<-5> to 10<-1>c<-1>.
