The temporary formation Of M6C during sintering of cemented carbides containing the cubic carbide (Ti,W)C is shown in samples exposed to interrupted sintering cycles. The M6C, revealed by magnetic-saturation measurements, X-ray diffraction and microscopy, is formed during the initial stage of sintering, but is dissolved as sintering proceeds. The overall carbon content does not change much between the sintering temperatures. It is believed that the initially nearly Aoichiometric (Ti,W)C releases carbon due to its equilibrium carbon content decreasing with increasing temperature, which makes dissolution possible. The temporary M6C would not normally be detected, since sample characterisation is in practice employed only after sintering.
