Abstract

A nickel-based superalloy without titanium and a corresponding powder. A process for producing a component, wherein the alloy or the powder is used, in particular for a process for additive manufacture, especially selective laser sintering or selective laser melting. A component having an alloy or produced from the powder or produced by the process.

Claims (35)

1. A nickel-based superalloy, wherein the alloying elements consist of in % by weight:

chromium (Cr): 12%-14%,

cobalt (Co): 9.5%-11.0%,

tungsten (W): 7.5%-9.5%,

tantalum (Ta): 1.5%-2.5%,

aluminum (Al): 4.5%-5.5%,

carbon (C): 0.04%-0.08%,

boron (B): 0.007%-0.01%,

hafnium (Hf): 0.4%-1.2%,

zirconium (Zr): 0.007%-0.01%; and

balance nickel (Ni),

wherein the nickel-based superalloy comprises no titanium (Ti).

2. The nickel-based superalloy of claim 1 ,

wherein the alloying elements consist of in % by weight:

chromium (Cr): 12.5%,

cobalt (Co): 10.5%,

tungsten (W): 8.5%,

tantalum (Ta): 2%,

aluminum (Al): 5%,

carbon (C): 0.05%,

boron (B): 0.009%,

hafnium (Hf): 0.5%,

zirconium (Zr): 0.009%; and

balance nickel (Ni),

wherein the nickel-based superalloy comprises no titanium (Ti).

3. A powder comprising: at least the nickel-based superalloy as claimed in claim 1 .

4. A powder comprising: the nickel-based superalloy consisting of the alloying elements of claim 1 .

5. A process for producing a component, comprising: producing the component with the nickel-based superalloy as claimed in claim 1 .

6. The process for producing a component of claim 5 , wherein additive manufacture, selective laser sintering, or selective laser melting is used.

7. A process for producing a component, comprising: producing the component with the powder as claimed in claim 3 .

8. The process for producing a component of claim 6 ,

wherein additive manufacture, selective laser sintering, or selective laser melting is used.

9. A component comprising: the nickel-based superalloy as claimed in claim 1 .

10. A component produced from the powder as claimed in claim 3 .

11. A component produced by the process as claimed in claim 5 .
