Abstract:

This report covers a study of metallic, multiple layer composite materials. Samples of Ag-Cr, Ag-Fe, Ag-Cu, Ag-Mg, Pb-Zn, Cd-Sn and Pb-Sn have been considered. Three fabrication techniques were considered--alternate evaporation in vacua, alternate electroplating and cold rolling of alternate layer stacks. Significant strength increases over pure and alloy materials have been observed for Ag-Cu and Pb-Zn composites. These strengths do not approach the theoretically predicted levels, but the authors feel that they do warrant further study. Author
