The mechanical behavior of Cu–Cr nanolayered films and an alloy film of nominal composition Cu20Cr80 at.% was studied by microcompression testing at temperatures from 25°C to 300°C. Comparing nanolayered films, plastic deformation and failure occurred at consistently higher stress levels in the film with the smaller layer thicknesses. Plasticity in the nanolayered films always initiated in the softer...
The yield strengths and deformation mechanisms of Cu–Cr nanolayered and alloyed thin films were studied by microcompression testing at elevated temperatures. The mechanical response of the films with alternating layers of Cu and Cr with sub-100nm interlayer thicknesses and alloyed films of the same average composition was compared to determine the role of the interfaces on deformation. Higher resistance...
