Abstract

Multilayerd Fe-Ag laminates were prepared by the repeated pressing-rolling and hot-sheath-rolling process. As starting materials, Fe sheets (30 or 60μm) and Ag sheets (30μm) were alternatively stacked. In this work, the metallographic structure and the mechanical properties were investigated. The strength of samples was evaluated by extension tests. As the layer thickness reduced, the yield stress became higher due to the grain size reduction and work hardening. The yield stress obeyed the Hall-Petch equation. The maximum yield stress was 850 MPa with 65 nm bilayer thickness, and in the sample of smaller layer thickness than that, strength slightly decreased. Anisotropy of strength was generated by rolling texture and recrystallization texture in the laminates. Strength and ductility varied with Fe and Ag volume ratios following the rule of mixture.
