| Abstract: | The temperature-strain rate domain of the Portevin-Le Chatelier (PLC) effect has been determined for three ultrafine grained aluminum alloys: Al-3Mg (А1), Al-4,57Mg0,35Mn-0,2Sc-0,09Zr (А2) and Al-5,4Mg-0,52Mn-0,1Zr (А3) (wt.%). The apparent activation energy of the serrated yielding was estimated. It was found that the presence of dispersed particles leads to a decrease in the activation energy and the temperature–strain rate domain of the PLC effect becomes narrower |
