1. A method for manufacturing a sintered body having one or more hard constituents in a form of a metal carbide with the general composition (Ti, Nb, Ta, W)C or combinations thereof, or in form of metal carbonitrides, in a metallic binder phase, the method comprising:
forming a green body from a powder composition including at least the one or more hard constituents, the metallic binder phase, and an organic binder system;
forming a pattern in a surface of the green body to provide a tag enabling individual identification of the green body, wherein forming the pattern comprises using a laser to selectively burn off the organic binder system with a marking speed of 500-3000 mm/s, thereby forming indentions in the surface; and
sintering the green body with the tag to form a sintered body having a smaller volume than the green body, wherein the pattern is formed such that the tag is readable after the sintering operation.
