Abstract

The microstructural characteristics and mechanical behavior at room temperature of a nanostructured Al-Mg alloy, with grain sizes of approximately 100 nm, manufactured by a cryomilling process were investigated in the present study. The results reveal an asymmetry of yield strength between tension and compression. On the basis of the mechanical behavior results it appears that the presence of a few micron inclusions may have a negative effect on tensile behavior of the cryomilled nanostructured Al-Mg alloy.
