摘要： A method for manufacturing a component having at least one internal cavity includes the step of providing a core element of metallic material that includes at least one cavity having a first opening covered by a cover element with a first and second side. A form partially surrounds the core element and cover element. The form is filled with metallic filling material and heated in a heating chamber that is pressurized with gas for a predetermined time period at a predetermined temperature and a predetermined isostatic pressure, so that a metallurgical bond is achieved between the core element, cover element and metallic filling material. The core element is arranged such that, after filling the form with metallic filling material, the second side of the cover element is covered with metallic filling material so that the cavity during heating is pressurized to the predetermined isostatic pressure.

摘要： The present invention relates to a method of making tungsten carbide powder by dissolving at least one organic or inorganic metal salt or compound of at least one of the groups IV, V, and VI of the periodic system preferably Cr, V, Mo and W in at least one polar solvent. Powder of WO3 is added to the solution, the solvent is evaporated, the remaining powder is heat treated in reducing atmosphere, mixed with carbon and carburized.

摘要： A method of making cemented carbide at which powders forming hard constituents and powders forming binder phase are wet milled together with a pressing agent is disclosed. The slurry is dried, preferably by spray drying, compacted into bodies of desired shape and sintered. A cemented carbide powder with a reduced compacting pressure at a predetermined weighing in of 18% shrinkage can be obtained by using from about 1 to about 3 wt-% pressing agent with the following composition: less than about 90 wt-% PEG and greater than about 10 wt-% of long chain C≧20 fatty acids, their esters and salts, in particular, erucic acid and/or behenic acid. The invention also relates to a cemented carbide powder with low compaction pressure.
