The structure of nickel superalloy ZhS6K-VI (the Ni – Co – Cr – Al – Ti – W– Mo – Nb system) after selective laser fusion (SLF) is studied. Structural components sensitive to the energy and rate of SLF parameters and to initial powder grain size are determined. Dependences of the geometric parameters and defects in the structure of the material after the SLF on grain composition of the powder and on the power and rate of the SLF are determined, and may be used for working out production regimes.

Additional information
In the opinion of the editorial board the term “selective laser fusion” is disputable. The word combination as a whole implies a production operation, and “fusion” signifies a result, and not a process. In Russian technical language there is no production operation “fusion”, it is melting, i.e., bringing a charge or workpiece to a melting temperature. A more suitable construction is “selective laser melting” (editor’s note).
