Research HighlightsMetallurgy Stacking fault mosaicBrent GrocholskiMetal alloys often get harder as you strain them because of the creation and entanglement of line defects. Pan et al. found a different mechanism for this strain hardening in a multi–principal element alloy at liquid nitrogen temperature. The alloy forms a mosaic of small stacking faults oriented in different directions instead of linear defects.
