Intermetallics disappearance rates and intrinsic diffusivities ratios in the Cu-Zn system at temperature 400oC Cu-Sn temperatures from 190oC to 250oC are analyzed theoretically using literature experimental data. Diffusion activation energies pre-exponential coefficients for calculated combining results.
Infrared spectroscopy has emerged as a premier experimental technique to probe enigmatic effects arising from strong correlations in solids. Herewe report on recent advances in this area focusing on common patterns in correlated electron systems including transition metal oxides, intermetallics and organic conductors. All these materials are highly conducting substances but their electrodynamic...
The effect of stir casting process on the modification of the Fe-containing intermetallics formed in a cast in-situ composite based on Al-319 matrix alloy was studied in the present work. Microstructural observations using optical and scanning electron microscopes showed that the undesirable needle-like shape of the Fe-containing intermetallics (β) and also the coarse star-like α com...

We propose a transferable machine-learning model based on the intrinsic descriptors, which can predict adsorption energies of single-atom alloys, AB intermetallics and high-entropy alloys , simply by training properties transition metals.
The 2XXX Al alloys are characterized by their superior mechanical properties resulting from alloying elements and precipitation hardening treatments. AA2524-T3 alloy was developed to replace the AA2024-T3 in aerospace industry. However, both present many intermetallic particles (IMCs) microstructure, this is main reason for high susceptibility localized corrosion (such as pitting stress crackin...
