A model that predicts the strength of turbine disk alloys with complex multimodal micrsotructures has been developed. This model accepts either experimental or computed information on chemistry, physical properties and a range of microstructural parameters and the overall strength of the material can be predicted. More importantly, the model predicts the contributions of specific features of the microstructure and the influence of spatial variations on local properties within a processed component. This type of information is particularly valuable for selection of heat treatments and has provided new insight to the importance of the smallest precipitates in this class of materials. |
