Alloying elements partitioning in TiAl-Ru intermetallic alloys

Intermetallics, 1999
Abstract Ruthenium additions are of interest for increasing low-pH resistance as well as improving mechanical properties of TiAl. Two phase Ti-48 at% Al-0.5 at% Ru was investigated. The partitioning behaviour of alloying elements in this condition was investigated by atom-probe field-ion microscopy (AP-FIM).

Thermodynamic Limits to Molecular Doping in Conjugated Polymers: A Perspective on Phase Behavior and Miscibility

Advanced Materials, EarlyView.
Molecular doping of conjugated polymers is fundamentally constrained by thermodynamic phase behavior. This Perspective reframes doping efficiency and stability in terms of miscibility limits, binodals, and solvus boundaries, highlighting the role of effective interaction parameters and charge transfer.
