Heterogeneous lamella structure unites ultrafine-grain strength with coarse-grain ductility, Wu, Yang, Yuan, Wu Wei, Huang, Zhu, PNAS, 2015
Novelty/impact/significance:
A novel heterogeneous lamella structure in Ti is created, which is as strong as the ultrafine-grained Ti and simultaneously as ductile as the coarse-grained Ti, with higher strain hardening than the coarse-grained Ti.
