4. Three-Dimensional Observation of Superlattice Domains in Ordering Alloys by DFTEM Tomography
This paper shows a technique to acquire a tilt series of dark-field transmission electron microscopy (DFTEM) images for superlattice domains formed in ordering alloys. Fundamental points are as follows 1) use of a superlattice reflection with a relatively long extinction distance (small structure factor) to satisfy the projection requirement and 2) careful realignment of the electron beam to keep the diffraction condition during tilting the specimen. Tomographic reconstruction from the obtained DFTEM tilt series visualizes three-dimensional morphology and distribution of the superlattice domains, demonstrating the feasibility of the DFTEM tomography..

Arya, Commencement of Ordering in Al–0.69Mg–0.31Si Alloy, Transactions of the Indian Institute of Metals, 10.1007/s12666-019-01844-4, 73, 301-308, 2019.11, Early stages of ordering in dilute Al–0.69(at.%)Mg–0.31(at.%)Si alloy, aged at 373 K for 120 h and 7200 h and at 453 K for 20 h, have been studied using scanning transmission electron microscopy techniques. Starting from the solute enrichment in (110)-type parallel planes, merely after 120 h of aging, isothermal growth at 373 K has been observed to lead to the formation of the small-ordered region after 7200 h of aging. Scanning transmission electron microscopy images from the aforesaid three varieties of samples and the corresponding Fourier-transformed images have been the basis to suggest the possible path of evolution of β″ ordering in this dilute alloy. Based on this, the present study reveals the mechanism of formation of silicon pillar, which is the early stage of β″ that transforms to a fully developed β″. This corroborates with the concept of getting the final β″-strengthened product from an under-aged alloy by a suitable heat treatment..
