The Influence of Deformation Modes on the Structure and Properties of Al-Mg-X Powder Composites. II. High-Alloyed Al-Mg Powder Materials

摘要

The influence of deformation modes on the structure and mechanical properties of powder materials produced from aluminum-magnesium alloys by ultrafast melt crystallization with high-pressure water atomization was studied. Extrusion of powder pellets onto a ribbon followed by its symmetric or asymmetric rolling was used as the deformation technique. The influence of the symmetric and asymmetric rolling modes on the mechanical properties of high-doped Al-11.2 Mg-2.2 Mn-0.6 Zr and Al-3 Mg-8 Fe-0.5 Zr powder materials was examined. It is shown that rolling significantly increases the strength of the resultant products, asymmetric rolling being more effective than symmetric one.
