This study investigated the effect of Sn addition on clustering behavior of natural aging (NA) in Al-0.95mass%Si-0.56mass%Mg-0.04mass%Sn alloys by XAFS measurements, first-principles calculation and Vickers hardness measurements. XAFS measurements...
Electrical resistivity and Vickers hardness of Alloy 625 due to cold rolling were measured, and, discussed with the microstructural change obtained using electron backscattered diffraction and X-ray diffraction. Both increase in dislocation densit...

Tensile mechanical properties of fully recrystallized TWIP steel specimens having various grain sizes (d) ranging from 0.79 μm to 85.6 μm were investigated. It was confirmed that the UFG specimens having the mean grain sizes of 1.5 μm or smaller a...
Magnetization (M) of binary Al-Mg alloys and intermetallic compounds were measured in the temperature (T) range from 10 to 300 K. The Al-rich alloys Al - 2, 3, 4, 5, and 10 at% Mg) revealed diamagnetic contributions to the magnetization correlatin...
This study investigated cluster formation in the early stages of natural aging in Al-1.04 mass%Si-0.55 mass%Mg alloys by soft X-ray XAFS measurements and first-principles calculation. XAFS measurements at the Mg-K and Si-K edges were carried out a...
