Optimization of strength and ductility in nanocrystalline and ultrafine grained metals
SCRIPTA MATERIALIA, 49(7), 657β662.
The possible optimization of strength and ductility in nanocrystalline and ultrafine grained metals is assessed. Most nanocrystalline metals show little ductility while exhibiting enhanced strength. The possibility that these properties can be optimized is discussed for microstructures with appropriate grain size distributions, and the introduction of second phase particles.
