Title (EN) METHOD OF MAKING ARTICLES OF TOOL STEEL POWDERS
(FR) PROCEDE DE FABRICATION D"ARTICLES DE POUDRE D"ACIER POUR OUTILS
Abstract: front page image
(EN)The proposed method relates to the powder metallurgy and is intended for making cutting tools, press tools as well as high safety construction parts. The method comprises introducing a powder into a capsule, sealing the capsule, heating it and subsequently extruding the capsule together with the powder. Before its sealing, the capsule with the powder is filled with nitrogen under a pressure of 1 to 5.105 Pa, then the capsule is sealed, heated up to a temperature of 700 to 1000 C after which the capsule is unsealed and heated up to a temperature of 1050 to 1200 C
(FR)Le procede concerne la metallurgie des poudres et est destine a la fabrication d"outils de coupe, d"outils de presse ainsi que des pieces de construction de grande securite. Le procede consiste a introduire une poudre dans une capsule, a fermer la capsule, a la chauffer puis a extruder la capsule avec la poudre. Avant de la fermer, la capsule avec la poudre est remplie d"azote sous une pression de 1 a 5,105 Pa, puis la capsule est fermee, chauffee jusqu"a une temperature de 700 a 1000 C apres quoi la capsule est debouchee et chauffee jusqu"a une temperature de 1050 a 1200 C.
