摘要： A method and apparatus for the heat treatment of hard metals, cermets and ceramics in a microwave sintering furnace, the material to be treated being moved together with the resonator relative to one or a plurality of microwave sources. The material to be treated is disposed in individual cassettes which, with the exception of an opening necessary for the microwave radiation, consist of material which is impermeable to microwaves and dimensioned to simultaneously form microwave resonant cavities at a microwave frequency when charged with the material.

摘要： A polygonal cutting insert is formed with a polygonal cutting face, an opposite support face generally congruent and generally parallel to the cutting face, and a plurality of generally planar side faces extending generally transversely between the cutting and support faces and meeting at corners. The side faces and corners define a cutting edge at a periphery of the cutting face and each side face is formed by at least two side-face regions extending parallel to each other and to the cutting and support faces and forming respective different side angles with the cutting face. Respective corner surfaces extending between the cutting and support faces at the corners each extend between a respective pair of side faces. Each such corner surface has a predetermined width that is greatest at the support face.

摘要： The invention relates to a hard metal substrate body consisting of a WC hard material phase and between 3 and 25 mass % of a binding phase containing at least one binding metal Fe, Co and/or Ni, and up to 15 mass % (in relation to the binding phase) of dissolved dopants from the group containing Al, Cr, Mo, Ti, Zr, Hf, V, Nb, Ta. The invention also relates to a method for producing one such hard metal substrate body, using powder metallurgy followed by sintering. According to the invention, the percentage of all of the dopants in the hard metal is limited to a maximum of 4 mass %, the proportion of cubic phase in the hard metal is less than 4 vol. %, and the binding metal content in an edge region of the hard metal substrate body falls from up to 1 μm, preferably up to 0.5 μm, to less than half the binding agent content inside the substrate body. In order to produce said hard metal substrate body, once the eutectic has been reached and at the latest once the sintering temperature has been reached in the heating phase, the vacuum or inert gas atmosphere is replaced by a N2 atmosphere and maintained at least until the sintering temperature is reached.
