Claim 0:
1. A method for producing metal-based alloy powders by means of centrifugal atomization in a closed chamber comprising the steps of:
a) providing a composition comprising at least one metal,
b) melting the composition, and
c) atomizing the molten composition by means of centrifugal atomization with an atomizing disk,
wherein the atmosphere in the closed atomization chamber is pressurized and/or cooled and wherein PA2 is between 4500000 and 70000000, wherein PA2=K1*PA1+K2*P, being P the absolute pressure in the atomization chamber in Pa, and PA1=ρ*N2*d2, wherein ρ is the density of the composition to be atomized at their melting point under 1 bar absolute pressure measured in kg/m3, N is the rotating speed of the atomizing disk in rad/s and d is the diameter of the atomizing disk in m, and K1=0.0033 in 1/Pa and K2=22 in 1/Pa.
