发明名称 Hårdmetallskär och metod att tillverka detsamma
摘要 The present invention relates to a method of making a cemented carbide body. The body is made using conventional powder metallurgical methods such as milling, pressing and sintering. According to the invention, a combined sintering process is used comprising at least a sequence where the batch of bodies in the sintering furnace is heated to a sintering temperature at least above the melting point of the binder phase. The batch of bodies in the sintering furnace is then allowed to cool down to a temperature at least below the melting point of the binder phase and kept there for at least from about 1 but preferably less than about 30 minutes and then heated up again to a sintering temperature at least above the binder phase melting point. The present invention also relates to a cemented carbide body made according to the method.
