WebMechanical Engineering questions and answers Cu-Pd system obeys Vegard's law, which states that the lattice constant changes linearly with composition. It is often used to determine the composition of a material system obeying Vegard's law. If the lattice constant of an CuzPd1-x alloy is 0.3700 nm, what is the composition of the alloy in atomic %. http://acshist.scs.illinois.edu/bulletin_open_access/v37-1/v37-1%20p42-49.pdf
