Type-B serrations were observed during room-temperature tensile deformation of Al-2.17mass%Mg alloy with an average grain size of 12 μm. Digital image correlation was used to visualize Portevin-Le Chatelier (PLC) bands, and microstructural changes...
This study investigated the cluster formation process in the early stages of 353 K aging in Al1.04 mass%Si0.55 mass%Mg alloys by means of soft X-ray absorption fine structure (XAFS) measurements and first-principles calculations. XAFS at the Si-K ...
An accumulative roll bonding up to 8 cycles increases ultimate tensile strength of Al-0.1at%Ni alloy around 2.5 times from around 60 MPa up to around 185 MPa. Whereas, electrical resistivity at 77 K increases less than 20% from 2.8 nΩm up to 3.3 n...
Chemically modulated mesoscopic domains in a fcc single phase CrMnFeCoNi equi-atomic high entropy alloy (HEA) are detected by small angle diffraction performed at a synchrotron radiation facility, whereas the mesoscopic domains cannot be detected ...
