| Abstract Scope |
Measuring orientation dependent creep properties is a high-cost experiment, which requires multiple single crystal specimens and an extra-long time. Nanoindentation creep can utilize the surfaces of polycrystal samples and significantly reduce the cost. In this work, constant contact pressure (CCP), an advanced nanoindentation creep method, was used to study the anisotropic creep properties of beta-Sn at room temperature. The statistical analysis of experimental results of over 12 grains will be presented. Continuum FEM was used to demonstrate the accuracy of the CCP method by showing the relationship between CCP-measured creep exponents and materials parameters. Crystal plasticity FEM results will be presented compared with experiments, to reveal the microstructural mechanism of room temperature indentation creep of beta-Sn. |
