| Abstract Scope |
This study investigates the effects of nanoindentation spacing and crystallographic orientation on the variability of mechanical properties in 1100 aluminum subjected to large plastic deformation and heat treatment to produce various grain sizes. The relationship between grain size and measured indentation area is analyzed to understand the influence of microstructure on localized mechanical response. Orientation effects are explored to assess anisotropy in nanoindentation behavior. In addition to Berkovich nanoindentation, spherical nanoindentation is employed to better capture the elastic–plastic transition behavior. Complementary techniques, including dynamic mechanical analysis, strain rate sensitivity testing, and creep characterization, are used to provide further insight into time- and rate-dependent deformation. Nanoindentation results are compared against bulk mechanical tests conducted at quasi-static strain rates, providing a comparison between localized and macroscopic mechanical behavior. This comprehensive approach offers valuable insights into the deformation behavior of commercially pure aluminum as a function of grain size and testing methodology. |
