"A multiscale mean field model for elastic properties of hypereutectoid pearlitic steels with different microstructures";
International Journal of Materials Research, 112 (2021), 5; 348 - 358.

Multiscale modeling of macroscopic elastic properties of pearlitic hypereutectoid steel using the Eshelby matrix-inclusion approach is possible. The model works through successive homogenization steps, based on the elastic properties of cementite and ferrite. Globular pearlite is homogenized using a Mori-Tanaka approach. Lamellar pearlite and pearlite colonies with fragmented proeutectoid cementite are homogenized by a classical self-consistent scheme. In the case of pearlite colonies surrounded by a continuous cementite film, a generalized self-consistent scheme is used. The influence of microstructural parameters such as the pearlite colony size or the thickness of the proeutectoid cementite on Young´s and shear moduli and on coefficients of the stiffness tensor is simulated. Proof of concept is obtained by comparison between predicted elastic behavior and experimental results from the literature.
