Abstract Scope |
Mille-feuille structured (MFS) materials, in which hard layers and soft layers are alternately laminated, exhibit high strengths by hot working. Although their strengthening mechanisms are still unclear, the inhomogeneous properties between the hard layers and the soft layers is accepted to be playing a large part. In the LPSO structure, the elastic properties of hard/soft layers can be estimated by macroscopic investigations of nearly single crystalline specimens, however it is difficult for MFS owing to their low degree of order. In the present study, we have investigated the elastic property of solute enriched layers in the MFS of Mg-Zn-Y alloy, based on STEM direct observations, the linear elastic model and first-principles calculations. We estimated Young's Modulus of Zn/Y enriched layers, based on the linear elastic model, resulting to suggest that Zn/Y enriched layers are indeed behave as hard layers in MFS Mg alloys. |
