Abstract

Finite element (FE) simulation of microstructure evolution was performed in the current work. The flow stress curve for FE simulation was obtained from tensile test whichwas carried out at room temperature. Samples were machined from a rolled sheet of AZ31B magnesium alloy. Simplified micro scale models were developed in order to study the influence of the round inclusion and twin-like inclusion on the material fracture behaviour. It was shown that fracture initiation point is dependent on the yield stress of the inclusion. Finally, polycrystalline model including ten grains of similar sizes was developed. The triple junction points were recognized as sites of fracture initiation.
