Films with modulated composition 8‐A˚ Cu/8‐A˚ Ni show an increase in the Young’s and torsional moduli of a factor of 2, relative to bulk or longer‐wavelength samples. The film structure is found to be highly textured with coherent lamella for the short‐wavelength‐enhanced moduli samples, but becomes more random with the probable introduction of misfit dislocations at longer wavelengths. The moduli results support the previous findings of Tsakalakos and Hilliard.
