NIST Ni-based diffusion mobility database

Abstract

The NIST Ni-based diffusion mobility database was originally constructed for the fcc phase of the Ni–Al–Co–Cr–Hf–Mo–Re–Ta–Ti–W system. Diffusion data in various constituent binary systems were assessed to establish a multicomponent diffusion mobility database. The diffusion assessment relied on an existing thermodynamic database for the calculation of needed thermodynamic factors. Later in 2004, Fe was added to the database, as well as estimate for the C diffusion. In 2008, the Ni-Al-Ti and Ni-Al-Mo diffusion assessments were updated. The diffusion mobility database is compatible with the NIST Superalloy database and other commercial thermodynamic databases.
