AN ATOM-PROBE ANALYSIS OF Al-Li ALLOYS
نویسندگان
چکیده
The aging process in A1-Li alloys was studied by an atom-probe FIM. Two types of precipitates were recognized in the FIM image, one is brightly imaged with a high degree of order in its structure and the other appeared dark against the Al matrix. Atom-probe analysis showed that the Li concentration is in a range of 10 to 25 at% in the dark precipitate and approximately 25 at% in the bright precipitate.

Advanced Nanostructural Analysis of Aluminium Alloys Using Atom Probe Tomography
This paper sets out the needs for and recent advances in microscopy in Al alloys, using solutesolute and solute-vacancy clustering as examples. Cluster-assisted nucleation and cluster strengthening are discussed and this is followed by a discussion of the local electrode atom probe. Heuristic and algorithmic tools for assessing the nanoscale microstructure or nanostructure of Al alloys acquired...
متن کاملDECOMPOSITION IN BINARY Al-Li ALLOYS
We have investigated the influence of aging on the morphology and phase composition of annealed Al-Li binary alloys by means of an atom probe with a multi-detection system. The influence of artifacts such as the preferential evaporation of the Li-atoms and the pile-up effects for the Al-atoms were analysed as well. Specimens of Al 2.0 wt%Li andAl -2.9 wt%Li were solution treated and aged at 190...

For both alloys, DSC analysis...
متن کاملClustering and Segregation of Mg and Ag Atoms during the Precipitation Processes in Al(-Li)-Cu-Mg-Ag Alloys
This paper reports three dimensional atom probe (3DAP) results of solute clusters and precipitates in early aging stages of Al-Cu(-Li) alloys containing small amounts of Ag and Mg atoms. In an as-quenched Al-1.9Cu-0.3Mg-0.2Ag (at.%) alloy, solute atoms are uniformly dissolved. On aging for 5 s at 180°C, Ag and Mg atoms form co-clusters. These co-clusters do not have well defined shape, but they...
متن کاملAtom Probe Tomography Investigations of Modi ed Early Stage Clustering in Si-Containing Aluminum Alloys
In this paper atom probe tomography is used to explore early stage clustering in aluminum alloys. Two novel concepts for a modi cation of clustering are discussed. Control of early stage clustering is welcome from an application point of view since clustering deteriorates strength evolution during the industrial heat treatment of the important class of Al Mg Si precipitation-hardenable alloys. ...
