摘要

•Size effects stem from the: indenter, grain size, and dislocation cells.•Varying size effects were found via analysis of annealed and unprocessed material.•Hardness dominated by contributions from cell structure and GB interaction.•Indentation effect limits spatial resolution of cells that can be characterized.
