Effect　of　milling　time　on　the　microstructure　and　mechanical　properties　of　Ti(C,N)-304　stainless　steel　cermet　and　the　fracture　mechanism　were　studied　in　this　work.　The　microstructure　was　investigated　by　means　of　x-ray　diffraction　(XRD),　scanning　electron　microscope　(SEM)　combined　with　energy　dispersive　spectrometer　(EDS),　and　field　emission　transmission　electron　microscope　(FETEM).　FETEM　and　EDS　were　also　used　to　analyze　the　Ti(C,N)/304ss　interface.　Mechanical　properties　such　as　transverse　rupture　strength　(TRS)　and　hardness　were　also　measured.　Results　show　that　prolonged　milling　time　decreases　the　Ti(C,N)　grain　size　and　improves　the　homogeneity　of　microstructure.　As　a　consequence,　the　frequency　of　intergranular　fracture　increased　and　it　can　improve　the　mechanical　properties.　Fe　and　Ti　elements　could　interdiffuse　and　the　hard　phase　was　closely　bonded　with　binder　phase.　The　Ti(C,N)/Ti(C,N)　interface　was　weaker　than　Ti(C,N)/304ss　interface.　Results　also　show　that　the　transverse　rupture　strength　and　the　hardness　increase　with　increasing　milling　time　and　the　maximum　values　were　obtained　at　18　h　with　1437　MPa　and　83.7　HRA,　respectively.
