摘要：
The present invention relates to a method for manufacturing a sintered body of carbonitride alloy with titanium as the main component and cobalt as the binder phase and which does not have any compositional gradients or center porosity concentration after sintering. This is achieved by processing the material in a specific manner to obtain a lower melting point of the liquid phase in the interior of the body than in the surface while balancing the gas atmosphere outside the body with the alloy composition during all stages of the liquid phase sintering.
