Abstract
Processing through powder metallurgy becomes the only feasible way for the most highly alloyed of high speed steels (HSS), with carbon contents between 0.7 wt % and 2.5 wt% containing substantial amounts of carbide formers W and/or Mo, V, Cr.
The basis of the project of the European collaborative study to arrive at the definition of new grades of HSS that meet the sintering temperature through “computer assisted design of sinter able tool steels”, is presented..
Résumé
L’élaboration en métallurgie des poudres devient la seule voie possible pour les plus alliés des aciers ultra rapides (HSS), avec des teneurs en car bone de 0.7% à 2.5% et contenant des quantités significatives de précurseurs de carbures tels que W et/ou Mo, V, Cr.
La base du projet de l’étude Européenne de collaboration pour trouver la définition de nouvelles nuances de HSS qui atteignent la temperature effective de frittage grâce à la « Determination d’ aciers à outils frittables assistée par ordinateur», est présentée.
