Analysis of Impurity Diffusion in Ordered Alloys and Intermetallic Compounds of the L12 Type
Published online by Cambridge University Press: 10 February 2011
Abstract
In this paper we present a new formalism for impurity diffusion in A3B alloys taking the L12 structure. We analyse two limiting cases, where impurities remain entirely on the α sublattice and where the impurities are distributed between the two sublattices but the actual mobility is largely confined to the α sublattice. Application is made to In diffusion in Ni3Al and Al diffusion (which may itself act like an impurity on the α sublattice) in Ni3Al.
