| Popis: | The mechanical properties of Ni-based superalloys are based on the hardening gamma-prime phase with an ordered structure. A solution for new phase precipitate growth is suggested for the case of the Ni-based alloys. In accordance with solution a mathematical model of gamma-prime phase precipitates growth during direct laser deposition, which is a type of DED-method, was developed in order to be able to predict the size of the hardening gamma-prime phase grains and thus the mechanical properties of the alloy. A series of experiments on depositing samples using Ni-based superalloys powder was carried out to verify this model. |
