Abstract:
A method for manufacturing a cemented carbide body (1), comprising the following steps: - forming a first part (2, 9, 14, 17) of a first powder composition comprising a first carbide and a first binder phase, - sintering the first part (2) to full density in a first sintering operation, - forming a second part (3) of a second powder composition comprising a second carbide and a second binder phase, - sintering the second part (3) to full density in a second sintering operation, - bringing a first surface (4) of the first part (2) and a second surface (5) of the second part (3) in contact, and - joining the first and second surface in a heat treatment operation.
