Step-controlled Brownian motion of nanosized liquid Pb inclusions in a solid Al matrix
(Pergamon-Elsevier Science Ltd, Oxford, 2017)
We have made direct observations of the Brownian motion of individual nanosized liquid lead inclusions in solid aluminum by in-situ transmission electron microscopy. The process was found to depend strongly on the size of ...
Mechanism and dynamics of shrinking island grains in mazed bicrystal thin films of Au
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
This work investigates the mechanism and dynamics of grain boundary migration driven by capillary forces via in situ electron microscopy, complemented by molecular-dynamics simulations. Using thin films of Au with the mazed ...
Dislocation glide-controlled room-temperature plasticity in 6H-SiC single crystals
(Elsevier Ltd, 2014)
In situ transmission electron microscopy observations of uniaxial compression of sub-300 nm diameter, cylindrical, single-crystalline 6H-SiC pillars oriented along 〈0001〉 and at 45° with respect to 〈0001〉 reveal that plastic ...
Twin nucleation from a single lt c plus a > dislocation in hexagonal close-packed crystals
(Acta Materialia, 2021)
Twinning plays an important role in governing the balance between strength and ductility in hexagonal-close-packed (HCP) metals. Here, we report a combined experimental and theoretical study of twin nucleation from a single ...
