A combinatorial study of the nickel-chromium system

Using recent work in combinatorial materials science as a background, a new method was developed to create a combinatorial alloy system. This method involved the electroplating of a film of selected geometry onto a metal substrate, followed by a heat treatment. Using this method, the nickel-chromium alloy system was created on specimens as small as 1 cm x 1 cm. A compositional map of these specimens was created using Energy Dispersive Spectroscopy in the Scanning Electron Microscope (SEM); the mechanical properties of this system were investigated using nanoindentation, and crystallographic information was obtained using Electron Backscattered Diffraction in the SEM.
