A diffusion mobility database for magnesium alloy development

Abstract: and Zn) systems was developed through the critical assessment of available Mg diffusion literature. Optimization of the binary diffusion activation energy terms for Ag, Al, Sn, and Zn solutes, as well as the Al-Zn interaction parameter were completed through the coupling of an existing thermodynamic database with the DICTRA software program. In general, agreement between simulated and experimental diffusion profiles was observed, although limitations for extrapolation to higher order systems were seen due to t… Show more

“…coefficients were only investigated in the Mg-Al-Zn system via the diffusion-couple method [79]. Based on the critical assessment of the limited available experimental information, a database of atomic mobility parameters for HCP Mg alloys binary systems was developed by Bryan [80]. However, there is not yet any available atomic mobility database for the HCP Mg alloys ternary systems.…”
