Influence of Cu volume fraction on the flow behavior of Fe based composites

This paper studied the flow behavior of two-phase Fe-Cu polycrystal using an elasto-viscoplastic material model based on micromechanics approach and finite-element simulations. In particular, three different iron (Fe) based composites are studied i.e., Fe-67 wt%Cu, Fe-50 wt%Cu and Fe-33 wt%Cu. To ob...

Summary:This paper studied the flow behavior of two-phase Fe-Cu polycrystal using an elasto-viscoplastic material model based on micromechanics approach and finite-element simulations. In particular, three different iron (Fe) based composites are studied i.e., Fe-67 wt%Cu, Fe-50 wt%Cu and Fe-33 wt%Cu. To obtain the initial crystal orientations of grains, a set of 1000 discrete random orientations are considered. The mechanical behaviour of the aforementioned polycrystalline was investigated by finite-element compression tests and micromechanical formulation compression tests. The results (finite-element and micromechanical formulation) showed that the flow behavior for these three kinds of Fe-Cu polycrystalline is in good agreement with the experimental stress–strain results.
