Abstract: Constant stress amplitude cyclic tests were conducted on monolithic Mg and Mg reinforced with 0.5, 1, and 2vol% of nano-size Y2O3. The cyclic life of the monolithic Mg and its nanocomposites were found to be comparable at the three stress amplitudes tested. Hardening behavior is observed throughout the whole fatigue life of all the specimens tested. Forest dislocations observed in Mg and Mg nanocomposites are responsible for the cyclic hardening. Addition of nanoparticles provides additional strengthening sources that cause the Mg-Y2O3 nanocomposites to harden more intensely that monolithic Mg. © 2008 SAGE Publications.
