Effect of 1Al addition on deformation behavior of Mg

Deformation behavior of 1Al containing Mg alloy has been investigated in the present study. After annealing, the Mg-1Al alloy shows a typical basal texture. When compared to the pure Mg having a similar texture and grain size, the Mg-1Al alloy shows much higher strength and larger elongation. Slip trace analyses of the tensile strained specimens show that non-basal slips such as pyramidal I and II slips can be easily activated at an early stage of deformation in the Mg-1Al alloy and the grains in the Mg-1Al alloy are seen to accommodate a larger degree of deformation than those in the pure Mg at a given strain. With increasing tensile strain, however, there is a strain localization along the initially formed slip lines of non-basal slips, forming surface steps without activating multiple slip lines.

Automated summary

The deformation behavior of a magnesium alloy containing 1% aluminum has been investigated in this study. The alloy shows much higher strength and larger elongation compared to pure magnesium with similar texture and grain size. Non-basal slips are easily activated in the Mg-1Al alloy at an early stage of deformation, leading to strain localization along the initially formed slip lines with increasing tensile strain.
