摘要： The invention relates to a cold work steel having a very high resistance to wear and good impact strength made powder-metallurgically through the consolidation of metal powder to a dense body. The powder has the following chemical composition expressed in weight-%: 0.5-2.5 C, 0.1-2 Si, 0.1-2 Mn, 0.5-1.5 N, max 15 Cr, preferably 6.5-11 Cr, max 4 Mo, max 1 W, 3-15 V, wherein up to half the amount of vanadium can be replaced by 1.5 times as much niobium, and part of the vanadium can be replaced by titanium at a content up to four times the content of nitrogen and the double amount of zirconium at a content up to eight times the content of nitrogen, and wherein the ratio V/(C + N) shall amount to not less than 2.5 and not more than 3.8, balance essentially only iron, impurities and accessory elements in normal quantities. The invention also relates to a method of manufacturing the steel. First there is made a steel powder having a composition as above with the exception of the nitrogen content. The nitrogen content in the powder is max 0.5 %. This powder is nitrided by means of nitrogen gas in the ferritic state of the steel at a temperature between 500° and 1000°C, preferably between 650° and 850°C during so long period of time that the nitrogen content in the steel is increased to an amount of between 0.5 and 1.5 % and such that the ratio V/(C + N) will be not less than 2.5 and not more than 3.8, and thereafter the powder is consolidated to a homogeneous body with full density.

摘要： In a process for making a consolidated body having a near net shape, a ceramic mold (13) is produced by casting a ceramic material against a mold (10), which has been made of a polymeric material, in order to obtain a mold cavity (17), the shape of which with a contraction equals the corresponding portion of the wanted body. The mold cavity (17) is filled with a metal powder (15) and/or other solid finely divided material and that said ceramic is placed in a deformable, gas-tight container (16, 16'), the walls of which directly or via a solid particle-type filling medium (19) are caused to lie close to the ceramic mold, and the container and its contents are heated and are subjected to an external isostatic pressure so that the ceramic mold and the finely divided material are compressed to a complete tightness.

摘要： Method of consolidation of a metal powder body to a completely dense body, in which a plate capsule (1c, 1d) consisting of a cylindrical wall and in one end thereof an end plate (2c, 2d) is charged with said powder so that the powder (3c, 3d) completely or essentially completely will fill the capsule, whereafter the air optionally is evacuated from the capsule and optionally replaced with a non-oxidizing protective gas, said capsule thereafter being closed also in the opposite end by an end plate, whereafter the capsule with its content is heated to a forging temperature suitable for the metal powder and is forged so that the powder is consolidated to a completely dense body. According to the invention the end plates (2c, 2d) are substantially prevented from bulging during the forging and thereby losing contact with the powder (3c, 3d) before the powder has been compacted to at least near complete density through stiffening of the central portions (6c) of the end plates (2c, 2d) by one or more stiffening members (7d), said stiffening member or members being welded to the inside of said respective end plate along a substantial length in order to stiffen said end plate, said stiffening member projecting into the powder body to an essential depth in order also to work as anchoring means for the end plate in the powder body.
摘要翻译：将金属粉末体固结成完全致密的体的方法，其中将由圆柱形壁组成的板胶囊（1c，1d）和其一个端部的端板（2c，2d）装入所述粉末中，完全或基本完全的粉末（3c，3d）将填充胶囊，此后空气任选地从胶囊抽空并且任选地被非氧化保护气体替代，此后所述胶囊也在相对端被端板封闭，然后将其含量的胶囊加热至适合金属粉末的锻造温度，并锻造，使粉末固结成完全致密的体。根据本发明，在锻造期间基本上防止端板（2c，2d）膨胀，从而在通过中心部分的加强将粉末压实成至少接近完全密度之前与粉末（3c，3d）失去接触（7d）通过一个或多个加强构件（7d）的端板（2c，2d）的端部（6c），所述加强构件沿着相当长度焊接到所述相应端板的内部，以便使所述端板变硬，所述加强构件突出到粉末体中至基本深度，以便作为粉体中端板的锚固装置。
