In the present study, nanoindentation studies of the 95.8Sn-3.5Ag-0.7Cu lead-free solder were conducted over a range of maximum loads from 20mN to 100mN, under a constant ramp rate of 0.05s−1. The indentation scale dependence of hardness was investigated. The results revealed that the hardness is dependent on the indentation depth. As the maximum holding load increased, which corresponded to an increasing indentation depth, a decreasing trend in the hardness was observed.

The variation of apparent hardness observed in previously reported Vickers indentation tests of metals is reexamined. Common deseriptions of the effect are shown to be inaccurate: the variation of apparent hardness is monotonic but not simple. The effect is consistent with varying size of a previously postulated “plastic hinge” at the perimeter of the indent. This complexity confers uncertainty on the estimation of characteristic macrohardness from small scale tests. Association of the indentation size effect with friction and with strain hardening is confirmed.
