A Positron Lifetime Study of Cooling and Natural Aging of Solutionized Aluminum Alloys

open access: yesAdvanced Engineering Materials, EarlyView.
The process during cooling of Al–Mg and Al–Mg–Si alloys from the solutionizing temperature down to 20 °C is interrupted. These states are analyzed with positron lifetime spectroscopy to trace the processes during cooling. In different temperature ranges, two stages of vacancy loss and solute clustering are identified.

Enhanced Oxidation and Thermal Shock Resistance of N‐type Mg2Si0.89(Sn0.1,Sb0.01) Thermoelectric Material via Cr0.9Si0.1 Coating

open access: yesAdvanced Engineering Materials, EarlyView.
Cr0.9Si0.1 protective coatings are developed to enhance the thermal‐shock and oxidation resistance of Mg2Si0.89(Sn0.1,Sb0.01) thermoelectric (TE) materials. The coating forms a dense and adherent barrier that suppresses oxygen diffusion and mitigates mechanical degradation during cyclic oxidation, demonstrating its potential to improve the long‐term ...
