| Popis: | The effect of deformation conditions on the structure and mechanical properties of powder materials based on aluminum-magnesium alloys produced by ultra-fast crystallization of a melt atomized by high-pressure water is studied. Extrusion of powder compacts into a strip that is then subjected to symmetric or asymmetric rolling is used as a deformation process. The effect of the rolling conditions on the mechanical properties of powder material AMg5 with Zr and Sc added is investigated. It is shown that the use of fractional rolling of strips made of AMg5 powder alloys significantly increases the ductility of the material and has a weaker effect on the strengthening; asymmetric rolling being more efficient than symmetric one. |
