Application of electron backscatter diffraction to the study of phase transformations

Abstract

615 ref. biblioInternational audienceThe application of the electron backscatter diffraction technique to the investigation of phase transformations is reviewed. The wide variety of results obtained using this technique is illustrated and discussed, focusing on thermodynamics and kinetics of phase transformations, solidification, solid state phase transformations, environmentally assisted reactions and thin film deposition. Emphasis is also placed on two rapidly growing developments: coupling electron backscatter diffraction with advanced experimental techniques and with more and more complex modelling of phase transformations and of resulting material properties

Influence of Spinodal Decomposition on the Plastic Behavior of Dynamic Electropulsing Treated ZA22 Alloy

“…The electron back-scattered Kikuchi diffraction patterns (EBKDP) are detected in SEM simply from bulk alloy specimens, rather than by using the transmission electron microscopy (TEM). 4,5) The EBSD can also facilitate …”

Dynamic Electropulsing Induced Phase Transformations in a Furnace Cooled Zn-Al Based Alloy (ZA22)

“…The EBSD can also facilitate evidence of phase transformation by discriminating between phases having close or even identical crystal structures. [25][26][27][28] An EBSD examination was carried out on the Leo 1530 FESEM using a commercially available software from HKL Technology APS Ltd. (Oxford, UK). In performing EBSD, the specimens were tilted at 70 degrees.…”

Guest Editorial: Personal perspective on microstructure of steels: 25th anniversary of MST and collection of papers in honour of Sir Robert Honeycombe

“…The advent of electron back-scattered diffraction (EBSD) 71,72 made it possible to examine the hypothesis that the good toughness of an acicular ferrite microstructure has its origin in the crystallographic dispersal of plates of ferrite. A marvellous paper by Gourgues et al 73 showed experimentally that highly misoriented plates formed from the same inclusion, so that the boundaries between plates represent formidable barriers to crack propagation.…”
