Popis: | Deformation of AZ61-F magnesium alloys with 1 wt % of Al2O3 phase was tested at different temperatures and different strain rates. It was shown that at temperatures 473–523 K and the highest strain rate applied from 1×10–2 s–1 to 1×10–4 s–1, a significant ductility growth was observed. The grain size of 0.6–0.8 μm was reached by severe plastic deformations by means of equal channel angular pressing (ECAP). Secondary Mg17Al12 and Al2O3 phases were identified. Maximum strain was gained at temperature of 473 K and strain rate of 1×10–4 s–1. |
