NICKEL-BASED SUPERALLOY WITH INCREASED OXIDATION RESISTANCE, POWDER, WELDING METHOD AND COMPONENT

A nickel-based superalloy with an increased oxidation resistance, power, and welding method, is provided. As a result of the addition of hafnium, no precipitation phases occur in the nickel-based superalloy and the proportions of chromium (Cr) and aluminium (Al) lead to a slightly reduced y′-content...

Zusammenfassung:	A nickel-based superalloy with an increased oxidation resistance, power, and welding method, is provided. As a result of the addition of hafnium, no precipitation phases occur in the nickel-based superalloy and the proportions of chromium (Cr) and aluminium (Al) lead to a slightly reduced y′-content, thus achieving good oxidation resistance and weldability.
