Beschreibung
Zusammenfassung:	The invention relates to the production of a material for tools and/or wearing parts which is tougher than conventional high-speed steel or hard metal alloys. By means of powder metallurgy, a structure is produced in which, in contrast to the situation in conventional high-speed steels, relatively hard regions (4) are partly or completely surrounded by a softer matrix (5). Such a "reverse structure" can be produced, for example, by employing a combination of high-speed steel powder particles and an austenitic binding phase formed from nickel-manganese or nickel-manganese-copper-alloys.
