Recycling　of　cemented　carbide　scraps　is　drawing　more　and　more　attention　to　companies　and　countries　all　over　the　world.　However,　the　recycling　method　has　always　been　a　problem　where　there　are　many　factors　involved.　The　feasibility,　recycling　rate,　energy　consumption　and　the　environment　conservation　are　all　significant　factors　for　the　recycling　method　that　need　to　be　considered.　In　this　work,　using　the　cemented　carbides　scraps　as　the　raw　material,　the　recycled　WC-16%Co　(mass　fraction)　composite　powder　was　synthesized　by　oxidation,　reduction　and　carbonization　reactions.　Then　the　recycled　composite　powder　was　sintered　to　prepare　the　hard　metal　bulks　by　sinter-HIP　(hot　isostatic　pressing).　The　results　indicate　that　with　the　carbon　addition　increases,　the　content　of　Co6W6C　in　the　composite　powders　decreases　while　the　total　carbon　and　free　carbon　increase.　When　the　carbon　addition　is　16.60%,　the　high-performance　hard　metal　bulks　can　be　obtained,　with　a　fracture　toughness　of　23.05　MPa.m(1/2)　and　a　transverse　rupture　strength　of　4020　MPa.　Moreover,　the　Co　phase　distributes　more　homogeneously　in　the　recycled　hard　metals.　The　larger　mean　free　path　of　the　Co　phase　and　the　lower　contiguity　degree　of　the　WC　grains　lead　to　the　high　performance　of　the　recycled　hard　metal　materials.
