ABSTRACT:
The present invention relates to a method of producing a sintered body comprising one or more hard constituents and a binder phase based on cobalt, nickel and/or iron by powder metallurgical methods milling, pressing and sintering of powders. At least part of the binderphase powder consists of non-agglomerated particles of spheroidal morphology having dimensions of 0.1 to 20 .mu.m.
