- Аннотация: A model for the porosity formation which occurs in single-crystal nickel-based superalloyswhen the non-equilibrium eutectic melts during high-temperature heat treatment is proposed. It isassumed that the porosity formation results from plastic deformation of the γ-solid solution of nickelcaused by dilatation of the melting eutectic. This mechanism of porosity formation is described analyticallyusing the elasto-plastic properties of superalloy experimentally measured at near solidus temperatures.The proposed model was used to predict the pore formation in the 3rd generation singlecrystalnickel-based superalloy CMSX-10. Comparison of the obtained theoretical and experimentalresults showed a good agreement.
