Plastic instabilities explored via acoustic emission during spherical nanoindentation

Popis výsledku v původním jazyce

The plastic instabilities of a silicon iron single crystal (Fe single crystal doped with 3 wt% of Si) were explored via spherical nanoindentation coupled with an acoustic emission detection at nano/micro-scale. Three possible scenarios were identified (gradually developing plasticity without detectable AE activity, sudden onset of plasticity with strong AE event, and an elastic response with frequent AE activity both during loading and unloading). Beside the irreversible dislocation slip, the reversible microstructural changes were identified that in turn provokes to extend the common definition of acoustic emission from a phenomenon caused by the sudden irreversible microstructural changes by including also reversible atomic reorganization. AE activity at nano/ micro-scale was for the first time observed during both the loading and the unloading for purely elastic indentations suggesting an action of reversible twinning.n
