ABSTRACT:
A sintered body of titanium based carbonitride alloy containing hard constituents based on, in addition to titanium, one or more of the metals Zr, Hf, V, Nb, Ta, Cr, No or W in 5-30% binder phase based on Co and/or Ni is disclosed. The body has a binder phase enriched surface zone with a higher binder phase content than in the inner portion of the body in combination with an enrichment of simple hard constituents, i.e., the share of grains with core-rim structure is lower in the surface zone than in the inner of the body.
