Abstract
The effect of addition of single walled carbon nanotubes (SWCNTs) on creep behaviour of Sn–3.8Ag–0.7Cu (SAC387) lead free solder alloy was investigated. The creep tests were carried out using indentation technique by means of a nanoindenter. Modified Garofalo’s creep model showed an excellent fit to the indentation depth versus time data and was used to extract the creep parameters. The results showed that the steady state creep rate as well as primary creep stage displacement and primary creep stage time decreased with increasing addition of SWCNT to the base alloy.
