Herein, we describe in detail a methodology to estimate the effective elastic parameters of nodular cast iron, using micro-tomography in conjunction with multiscale finite elements. We discuss the adjustment of the image acquisition parameters, address the issue of the representative-volume choice, and present a brief discussion on image segmentation. In addition, the finite-element computational implementation developed to estimate the effective elastic parameters from segmented microstructural images is described, indicating the corresponding computational costs. We applied the proposed methodology to a nodular cast iron, and estimated the graphite elastic parameters through a comparison between the numerical and experimental results.

Nodular cast iron is the cast iron that has nodular graphite spherical structure distributed in ferrite or pearlite matrix or in both of them. Recently, this material is used widely in industries because its low cost and better performance. The advanced metal industries nowadays have found some new technologies in order to improve the properties of materials. One of them is the addition of another elements into the base metals, such as nickel. The effects of the addition 1wt %, 2wt % and 3wt % nickel into nodular cast iron 50 on tensile and hardness properties were investigated in this study. The experimental results show that the best amount of nickel that added into nodular cast iron is 3% wt, which has the best tensile and hardness properties
