Advancing small‐angle X‐ray scattering for complex metallic systems: Ti2Cu precipitation in a martensitic near‐α Ti alloy

open access: yesJournal of Applied Crystallography, Volume 58, Issue 6, Page 2006-2017, December 2025.
A novel small‐angle X‐ray scattering modelling approach is introduced for the analysis of precipitation behaviour in metallic systems exhibiting scattering signals with streaks originating from the embedding matrix. This approach enables in situ tracking of the microstructural evolution, such as the volume fraction and size of second phases, during ...

Hot Tearing in Directionally Solidified Ni-Base Superalloys

open access: yesSuperalloys 2004 (Tenth International Symposium), 2004
The hot tearing mechanism has been studied in directionally solidified (DS) Ni-based superalloys with columnar grain structures. Castability tests and optical metallography of quenched samples were employed to explore the effect of microstructural evolution, grain boundary characteristics on the susceptibility of hot cracking formation during DS ...
