Influence of Platinum and Palladium on Diffusion in β-NiAl Phase

Article Preview

Abstract:

A new inverse method is applied for the determination of interdiffusion coefficients in b- NiAl(Pt) and b-NiAl(Pd). The results show that substitution of Pt or Pd to b-NiAl accelerates the diffusion of aluminium. Within the studied composition range and for Al-poor aluminides, the cross coefficients are negligible except for high Pd contents
