Abstract


A new methodology is proposed in the article for finite-element modeling and calculation of stress-strain characteristics of representative volumes of precipitation-hardening alloys, which contain inclusions of a strengthening phase. The methodology allows to take into account elastic interphase deformations, which take place at the interphase regions of the alloys under consideration. These deformations are results of specific volume mismatch of matrix and inclusion phases. The proposed methodology was used for modeling and calculation of stress-strain characteristics and elastic properties of a representative volume of the typical precipitation-hardening Ni-Cr-based alloy. It was shown that elastic interphase deformations increase significantly the level of stresses in the alloy under consideration. But they don’t influence considerably on elastic properties of the material. The proposed methodology may be used for modeling and calculation of stress-strain characteristics and mechanical properties of alloys, which contain strengthening particles.
