Abstract

The fatigue life and internal friction of neon- and nitrogen-implanted specimens of copper were measured.

The fatigue life is found to increase significantly (by about 50%) and scanning electron microscopy shows that the dislocation activity is markedly suppressed. The internal friction results are consistent and show that there is a pronounced overall reduction in the loss at the fatiguing temperature (300 K) owing to a reduction in dislocation mobility.

The internal friction results also show the existence of two new internal friction peaks at 150 and 170 K, which are produced by ion implantation. The results indicate that a defect complex may be responsible, rather than a defect dislocation interaction.

Ion implantation is also shown to increase the magnitude of the Bordoni peak at about 50 K in previously deformed samples.
