Young's Modulus of Iron–Silver Sheet Composites

Abstract

Layered iron–silver sheet composites were prepared by hot extrusion and cold rolling of powder mixtures of various compositions. These in-situ deformation composites show a strong increase in Young's Modulus on addition of silver to pure iron and their elastic behaviour is anisotropic in the rolling plane. The deformation dependence of Young's Modulus as well as the planar anisotropy are discussed with a new theory of Bunge, which covers the experimental findings sufficiently.
