Dendrite spacings in directionally solidified superalloy PWA-1480
Materials Science and Engineering: A, 1991 Abstract Primary dendrite spacings and side-branch coarsening kinetics were examined in specimens of the single-crystal multicomponent commercial superalloy PWA-1480, which were directionally solidified in a positive thermal gradient. The experimentally observed dependence of primary dendrite spacings and side-branch coarsening kinetics on growth ...

Deformation‐Induced Formation of Stray Grains in Additive Manufacturing of Single Crystals
Advanced Science, EarlyView.Stray grain formation severely limits the additive manufacturing of single‐crystal alloys. By integrating in situ synchrotron techniques, ex situ characterization, and multi‐scale multi‐physics modeling, the authors reveal that stray grains originate from dislocations at the solid‐liquid interface, rather than thermal supercooling in conventional ...
