To investigate the hardness indentation size effect (ISE) phenomenon,combining the nano-indentation technique and atomic force microscopy,load-depth curves and indentation images were obtained,and the plastic work in indentation process,max indentation depth,plastic deformation area and plastic deformation volume were calculated from these curves and images.

The initial plastic deformation of single crystal aluminium was simulated to study the indentation size effect in the nanoindentation test by using quasicontinuum method.

Tests performed using a Knoop indenter geometry reveal that there is an indentation size effect (ISE), namely that the apparent microhardness decrease significantly with increasing indentation test load.
