Origin of Anomalous Slip in Tungsten

Helena Van Swygenhoven, Cécile Renée Maria Marichal, Steven Van Petegem

Low-temperature deformation of body-centered cubic metals shows a significant amount of plastic slip on planes with low shear stresses, a phenomenon called anomalous slip. Despite progress in atomistic modeling of the consequences of complex stress states ...

{110} Slip with {112} slip traces in bcc Tungsten

Helena Van Swygenhoven, Camelia Borca, Cécile Renée Maria Marichal, Steven Van Petegem

While propagation of dislocations in body centered cubic metals at low temperature is understood in terms of elementary steps on {110} planes, slip traces correspond often with other crystallographic or non-crystallographic planes. In the past, characteriz ...

Nanoprecipitates in single-crystal molybdenum-alloy nanopillars detected by TEM and atom probe tomography

Helena Van Swygenhoven, Cécile Hébert, Barbora Bártová, Emad Oveisi, Cécile Renée Maria Marichal

Transmission electron microscopy (TEM) supported by various chemical analyses techniques as well as atom probe tomography is applied to characterize newly identified nanosized precipitates in Mo-alloy nanopillars that were prepared by directional solidific ...

Plasticity in bcc single crystals investigated by Laue diffraction during micro-compression

Cécile Renée Maria Marichal

Body-centered cubic metals are of high technological interest: for example tungsten as potential plasma facing component in future fusion reactors, molybdenum employed in aircraft parts, niobium as superconducting magnets, etc. The characteristics of their ...

Slip in directionally solidified Mo-alloy micropillars - Part I: Nominally dislocation-free pillars

Helena Van Swygenhoven, Camelia Borca, Cécile Hébert, Barbora Bártová, Emad Oveisi, Cécile Renée Maria Marichal, Steven Van Petegem

In situ Laue analysis during microcompression reveals plasticity in [0 0 1]-oriented, directionally solidified Mo alloy pillars to start with slip on the {1 1 2} < 1 1 1 > system having the highest Schmid factor followed by slip on the (1 1 0) plane contai ...
