SEGREGATION AT SPECIAL GRAIN BOUNDARIES IN Fe-Si ALLOY BICRYSTALS
The segre ation of silicon to the C=3, 112) and C=S, (013) symmetrical grain boundaries 1 was studied in well-fefined bicrystals of an Fe-l .9 at%Si alloy annealed in the range 773 1173 K using Auger electron spectroscopy. The segregation enthal y, AI1 = -8.1 * 0.5 kJ/mol, and entropy, AS = -69 r 0.4 i/(mol K), were determined for the (013f grain boundary in the temperature range 973 1173 K. Fo...
متن کاملStress-driven migration of simple low-angle mixed grain boundaries
We investigated the stress-induced migration of a class of simple low-angle mixed grain boundaries (LAMGBs) using a combination of discrete dislocation dynamics simulations and analytical arguments. The migration of LAMGBs under an externally applied stress can occur by dislocation glide, and was observed to be coupled to the motion parallel to the boundary plane, i.e. tangential motion. Both t...
متن کاملTransition between Low and High Angle Grain Boundaries
Institut für Metallkunde und Metallphysik, RWTH Aachen, 52056 Aachen, Germany Carnegie Mellon University, Pittsburgh PA 15213, USA Abstract The migration of planar, symmetric tilt grain boundaries with different tilt axes was investigated. The driving force for the grain boundary migration was due to an external mechanical stress field. Low as well as high angle grain boundaries can move under ...

متن کاملSegregation of calcium to magnesium oxide grain boundaries
Grain boundary (GB) segregation has been measured in Ca-doped MgO by examining intergranular fracture surfaces with Auger electron spectroscopy. The measurements reveal several interesting features. The composition of any given GB on the fracture surface is almost uniform, except for small variations due to deviations from planarity. There is a strong anisotropy of GB composition, which can amo...
