METHOD FOR PRODUCING OBJECTS FROM IRON-COBALT-MOLYBDENUM/TUNGSTEN-NITROGEN ALLOYS

The disclosure relates to a production of a semi-finished product for a manufacturing of objects, particularly tools, from a precipitation-hardenable alloy having a composition in wt.% of Co = 15.0 to 30.0, Mo up to 20.0, W up to 25.0, Fe and manufacturing-specific impurities as a remainder. To achi...

Beschreibung
Zusammenfassung:	The disclosure relates to a production of a semi-finished product for a manufacturing of objects, particularly tools, from a precipitation-hardenable alloy having a composition in wt.% of Co = 15.0 to 30.0, Mo up to 20.0, W up to 25.0, Fe and manufacturing-specific impurities as a remainder. To achieve an economical, highly precise production of objects or tools of the above alloy with reduced effort, it is provided to prevent a formation of ordered structures of the Fe atoms and Co atoms in the matrix of the type (Fe+(29xCo)) + approximately 1 wt.% Mo of the semi-finished product by a thermal special treatment, to thus improve a workability of the material.
