摘要： The invention provides a method for manufacturing sintered parts, which uses as a debinder solvent a substance harmless to the human body and which can enhance the strength of an injection-molded product. Sintered parts suitable for use in industrial production processes and, moreover, extremely high in strength of injection-molded parts, can be produced by the steps of: mixing at least one of a sintering inorganic powders of a metal powder, a metal carbide, a carbon-nitride, a nitride powder and a ceramic powder, with an organic binder composed of an organic substance soluble in an alcohol series solvent and an organic substance insoluble in the same; injection-molding the composition obtained by the preceding process into a metal mold of a sintered part shape; immersing the injection-molded product obtained by the preceding step into an alcohol series solvent to elute and remove part of the organic binder; and heating the product to remove the residual organic binder and sintering the same, wherein the portion soluble in the alcohol series solvent of the organic binder accounts for 30 to 70% of the binder.

摘要： A nitrogen-containing sintered hard alloy in which the content of the binder phase is at the highest level in an area to a depth of between 3 .mu.m and 500 .mu.m from its surface and its content in this area is between 1.1 and 4 times the average content of the binder phase in the entire alloy. Below this area, the content of the binder phase decreases gradually so that its content becomes equal to the average content of the binder phase at a depth of 800 .mu.m or less. The content of the binder phase in the surface layer is 90% or less of its maximum value. The depth of 800 .mu.m is a value at which the thermal conductivity is kept sufficiently high and at the same time a tool can keep high resistance to plastic deformation during cutting.

摘要： A throw-away tipped drill has an insert removably connected to a shank for cutting a workpiece. The insert (31) and the shank (32) have mutually engaging surfaces respectively, and a slit (34, 39) is formed either in the insert (31) or in the shank (32) for mounting the insert to the shank, whereby the insert (31) is fixed to the shank (32) by an elastic force which is caused by an elastic deformation upon mutual movement of opposite surfaces of this slit (34, 39) in engagement of the insert (31) and the shank (32). Therefore, the insert (31) and the shank (32) are coupled by simple press fitting without any requirement for a screw or other connection, whereby the assembly is improved. The cutting edge of the insert (31) has an excellent wear resistance, adhesion resistance and thermal cracking resistance and the shank (32) has an excellent toughness while the drill is relatively low in costs, by employing surface-coated cemented carbide as the material for the insert while employing steel as the material for the shank.

摘要： A hard sintered component of a cemented carbide or a stellite alloy having a complex three-dimensional shape and a small hole or the like and the high strength originally provided by the used material for making the component without any secondary working, is formed by injection molding a compact molding die having an inner mold surface roughness R.sub.max of not more than 3 .mu.m. Where a core pin is used the outer surface of the pin has a surface roughness R.sub.max of not more than 3 .mu.m. The compact is then sintered. The hard sintered component is composed of a cemented carbide or a stellite alloy. In such a hard sintered component, the surface of a complex three-dimensional shape such as a disc portion or a thin portion, or the inner surface of a small hole, is defined by a sintered surface which has a surface roughness R.sub.max of not more than 4 .mu.m.

摘要： Disclosed is a method of preparing a cemented carbide or a cermet alloy by mixing and kneading cemented carbide powder or cermet alloy powder with an organic binder, shaping this mixed powder into a prescribed configuration by an injection molding method and thereafter removing the organic binder from this compact and sintering the same, in order to obtain a dense alloy. Removal of the organic binder is performed in a first step in an inert gas atmosphere as a first removal step, and then continued in a second step in a vacuum of not more than 1 Torr. In the first removal step, the pressure is held in excess of the atmospheric pressure, to prevent the formation of imperfections in the compact. After continuous pores are formed in the interior of the compact, the atmosphere pressure is brought close to a vacuum, thereby facilitating the evaporation of gas from the surface and desorption of gas generated in the interior of the compact.
