Thin films of metals were described by a number of investigators to have extremely high mechanical strength. The program is aimed at determining the potential usefulness of composites made up of alternating thin films of a metallic substance and an amorphous nonmetal. In this phase of the work, methods of specimen preparation, measurement, and bulge testing to determine mechanical properties were established for thin metallic films and measurements were made of films of aluminum 200-870A thick and of titanium 200-750A thick. Estimated ultimate strengths of the aluminum films ranged from 50 to 92 kpsi and those of the titanium films from 93 to 150 kpsi, the highest value representing the thinnest film. Author
