Abstract
This study proposed a constitutive equation to predict the change in yield strength according to the behavior of β″ metastable precipitates, which have a profound effect on strength among materials precipitated during the T6 heat treatment of Al-Mg-Si alloy. The β″ precipitate is a metastable phase before it becomes a..... More

Abstract
The microstructure, mechanical properties and residual stress of flux-cored arc welded ASTM A516-70N carbon steel using a Mn-based low-temperature transformation (LTT) welding consumable were investigated. Microstructural analysis with X-ray diffraction, an electron backscattered diffractometer and a field-emission scanning electron microscope showed that the LTT weld metal was made up of..... More

Abstract
The effects of adding CO₂ to low level H₂S containing aqueous environment on the corrosion and hydrogen penetration behaviors of high-strength steel were evaluated using a range of experimental and analytical methods. The corrosion rate of the steel sample exposed to a low level of H₂S dissolved in an aqueous..... More

Abstract
Transparent and conductive Ti-doped In₂O₃ (TIO)/Ag/Ti-doped In₂O₃ (TAT) multilayer films were deposited on colorless poly imide (CPI) substrates by direct current (DC) and radio frequency (RF) magnetron sputtering at room temperature. During deposition the thickness of both the top and bottom TIO layer was fixed at 30 nm, while the..... More

Abstract
Sintered M-type hexaferrites with the chemical formula of Sr_0.3Ca_0.4La_0.3Fe_9.8Co_0.2-xMn_xSi_0.135O_19-d (x = 0, 0.05, 0.1, 0.2) and Sr_0.3Ca_0.4La_0.3Fe_9.8-yCo_0.2Mn_ySi_0.135O_19-d (y = 0.05, 0.1, 0.2) were prepared by conventional solid station reaction routes. A high sintering density of more than 95% of the theoretical density was achieved in all hexaferrite samples when calcination..... More

Abstract
Tetrahedrite is a promising thermoelectric material mainly due to its low thermal conductivity, a consequence of its complicated crystal structure. However, tetrahedrite has a high hole concentration; therefore, optimizing carrier concentration through doping is required to maximize the power factor. In this study, Te-doped tetrahedrites Cu₁₂Sb_4-yTe_yS₁₃ (0.1 ≤ y ≤..... More

Abstract
The bonding properties of adhesives are mainly affected by surface roughness, topography and chemical adsorption. In this paper, we studied the effects of surface pretreatment of Al 2024-T3 (bare) in terms of surface roughness, topography and surface free energy. Surface pre-treatment included solvent cleaning, FPL etching, PAA and CAA treatment...... More

Abstract
In recent years, human-convenient smart wearable devices have attracted considerable attention as emerging applications in smart healthcare systems, soft robotics, and human-machine interfaces. In particular, resistive film heaters with mechanical flexibility and excellent mechanical and electrothermal performance have recently been widely explored for wearable thermotherapy applications. Here, we present a..... More

Abstract
The effect of the heat treatment on the Mg₂Si phase in Al-Mg-Si alloy was investigated by a laser flash apparatus (LFA), Differential scanning calorimetry (DSC) and corrosion test. The alloy samples were solution treated at 590 ^oC for a half hour followed by warm water quenching, and then aged in..... More
