Irreversible evolution of dislocation pile-ups during cyclic microcantilever bending
Dávid Ugi, Kolja Zoller, Kolos Lukács +5
In metals geometrically necessary dislocations (GNDs) are generated primarily to accommodate strain gradients and they play a key role in the Bauschinger effect, strain hardening,…

Irradiation-induced strain localization and strain burst suppression investigated by microcompression and concurrent acoustic emission experiments
Dávid Ugi, Gábor Péterffy, Sándor Lipcsei +4
Plastic deformation of microsamples is characterised by large intermittent strain bursts caused by dislocation avalanches. Here we investigate how ion irradiation affects this phen…

Dislocation Avalanches: Earthquakes on the Micron Scale
Péter Dusán Ispánovity, Dávid Ugi, Gábor Péterffy +7
Compression experiments on micron-scale specimens and acoustic emission (AE) measurements on bulk samples revealed that the dislocation motion resembles a stick-slip process - a se…
