The effects of ion implantation on the fatigue behavior of metals.

摘要

The effects of ion implantation on the fatigue behavior of metals were investigated. High stacking fault energy FCC materials of aluminum and copper, low stacking fault energy FCC material of austenitic stainless steel and HCP material of titanium were ion implanted by boron or nitrogen at energies of 50 KeV to 3 MeV. The doses were from 10;Cracks nucleated at these slip bands and propagated along them. A composite model is presented to qualitatively analyze the effect of ion implantation on fatigue strength.
