The ongoing efforts to improve strength and ductility through miniaturizing specimens 1 or by forming sub-micrometer scale microstructure 2,3,4 bring with it the need to deeply understand mechanical ...
Refractory high-entropy alloys (RHEAs) are of interest for ultrahigh-temperature applications. To overcome their drawbacks — low-temperature brittleness and poor creep strength at high temperatures — ...
Today’s commercial SiC substrates are riddled with these atomic-scale imperfections, with thousands threading through each ...
Jogs and kinks are atomic scale changes in direction of a dislocation line. Jogs are out of the slip plane and kinks lie in the dislocations slip plane. For the edge dislocation shown, the jogs are of ...
· The Mixed dislocations is the most general type of unit dislocation and has an arbitrary angle between its line vector and Burgers vector. b is a constant of the dislocation. · The dislocation line ...
