Strengthening materials by engineering coherent internal boundaries at the nanoscale
K Lu, L Lu, S Suresh - science, 2009 - science.org
Strengthening materials traditionally involves the controlled creation of internal defects and
boundaries so as to obstruct dislocation motion. Such strategies invariably compromise …

Growth twins and deformation twins in metals
This article reviews recent basic research on two classes of twins: growth twins and
deformation twins. We focus primarily on studies that aim to understand, via experiments …

Strength and plasticity of nanolaminated materials
The mechanical behavior of nanolaminates is dominated by interfaces that act as sources,
barriers, and preferred sites for storage and dynamic recovery of glide dislocations. In this …

Detwinning mechanisms for growth twins in face-centered cubic metals
Using in situ transmission electron microscopy, we studied the stability of growth twins. We
observed the rapid migration of incoherent twin boundaries (ITBs), indicating that nanotwins …
