Controlling plastic instability
Source abstract
Abstract
Nanocrystalline alloys with grain sizes less than 100 nanometres are very strong, but tend to fail rapidly during plastic deformation. A new composite alloy with an unusual microstructure is able to achieve high plasticity by controlling the instabilities responsible for early failure.
