Streszczenie

While the elastic properties of a composite microstructure are relatively straightforward in obtaining (e.g., using the resonance ultrasound spectroscopy), the features of a single grain are not directly measured. Here, we show our approach to determining these properties by employing large-scale ab-initio modeling techniques. Furthermore, we quantitatively reproduce the observed values of the whole microstructure, basing our model-grain compositions on the X-ray diffraction patterns, thus substantiating the utility of this procedure in the design of novel alloys.
