The phenomenon of thermal diffusion (Ludwig-Soret effect) has been observed in three solid binary alloys, aFe-N, o;Fe-C, and Au-Cu. The interstitial solutes migrate to the higher temperature region of the specimen., as also does Cu in Cu-Au. The quantity, heat of transfer, appearing in the thermodyn
## Abstract Platinum is added to thermal barrier coatings (TBCs) as it is observed empirically to extend their lifetime, but the mechanism by which Pt acts is unknown. Since Pt has been proposed to alter diffusivities in NiAl, a key component of TBCs, we use firstβprinciples quantum mechanics calcu
