Beschreibung
Zusammenfassung:	Turbine blade has a tensile strength Rm of at least 700 N/mm , a creep limit Rp0.2, an expansion A of at least 15% and a constriction Z of at least 10%. The blade is produced from a powder metallurgical feed material formed by pulverizing a melt by atomizing with nitrogen and hot isostatically pressing the powder; machining and thermally treating or tempering.
