Grain boundary diffusion in severely deformed Al-based alloy

, 2017
Grain boundary diffusion in severely deformed Al-based AA5024 alloy is investigated. Different states are prepared by combination of equal channel angular processing and heat treatments, with the radioisotope $^{57}$Co being employed as a sensitive probe

Finding unprecedentedly low-thermal-conductivity half-Heusler semiconductors via high-throughput materials modeling

, 2014
The lattice thermal conductivity ({\kappa}{\omega}) is a key property for many potential applications of compounds. Discovery of materials with very low or high {\kappa}{\omega} remains an experimental challenge due to high costs and time-consuming ...

Influence of thermomechanical loads on the energetics of precipitation in magnesium aluminum alloys [PDF]

, 2020
We use first principles calculations to study the influence of thermomechanical loads on the energetics of precipitation in magnesium-aluminum alloys. Using Density Functional Theory simulations, we present expressions of the energy of magnesium-aluminum

Tuning the LPSO-dominated microstructure for strength increment of wire arc-directed energy deposited VWZ104K magnesium alloy

Review of Materials Research
Long-period stacking ordered (LPSO) phase endows Mg-Gd-Y-Zn-Zr magnesium alloys with improved mechanical property. Here, the Mg-10Gd-4Y-1Zn-0.5Zr (wt.%) alloy is fabricated by wire arc-directed energy deposition (WA-DED), and the microstructure dominated

The bi-layered precipitate phase zeta in the Al-Ag alloy system

, 2017
The Al-Ag system is thought to be a well-understood model system used to study diffusional phase transformations in alloys. Here we report the existence of a new precipitate phase, zeta, in this classical system using scanning transmission electron ...
