Transmission Kikuchi Diffraction (TKD), also sometimes called transmission electron backscatter diffraction (t-EBSD), is a method for orientation mapping at the nanoscale.. It’s used for analysing the microstructures of thin transmission electron microscopy (TEM) specimens in the scanning electron microscope (SE
20 November – A study of censorship in science finds it to be often driven by scientists themselves, motivated by prosocial concerns or reputation protection. [617] 22 November – An autonomous excavator is demonstrated. Using sensors, the machine can generate 3D maps of a construction site, localising individual blocks and stones in order ...
Calculated metastable miscibility gap in the Fe-Cr binary system (remake of [16] [17]) [1]. Duplex stainless steel can have limited toughness due to its large ferritic grain size, and its tendencies to hardening and embrittlement, i.e., loss of plasticity, at temperatures ranging from 250 to 550 °C (482 to 1,022 °F), especially at 475 °C (887 °F).

PSB structure (adopted from [7]). Persistent slip-bands (PSBs) are associated with strain localisation due to fatigue in metals and cracking on the same plane. Transmission electron microscopy (TEM) and three-dimensional discrete dislocation dynamics (DDD [8]) simulation were used to reveal and understand dislocations type and arrangement/patterns to relate it to the sub-surface structure.
