Abstract
Zirconium-based alloys, widely used for nuclear fuel cladding, are highly susceptible to hydrideinduced embrittlement. The degree of the hydride embrittlement is strongly affected by not only its concentration but also its morphology. The hydride can drastically reduce the mechanical properties of the cladding, especially when it is radially precipitated. Recently..... More

Abstract
The toughness and creep strength of Mod. 9Cr-1Mo steel, a ferritic heat resistant steel, are closely related to the amount of delta ferrite remaining in the weld. This study compared the amount of retained δ ferrite in the laser beam (LB) weld with low heat input and the gas tungsten..... More

Abstract
This research focused on the development of the part unit evaluation for an organic coated automotive lower arm using the electrochemical cyclic corrosion test (E-CCT). The E-CCT accelerates both the coating degradation and the perforation corrosion. The applied potential for the coating degradation was determined to be -500 mV_SCE for..... More

Abstract
WC-Co coatings manufactured by high velocity oxy-fuel (HVOF) spraying have a superior hardness and wear resistance. In this study, HVOF-sprayed WC-12Co coatings from three different feedstock powders were evaluated in terms of microstructural features, carbide decomposition and erosion resistance. The fused-crushed and the sintered-crushed WC-12Co powders had an angular shape,..... More

Abstract
This study manufactured Fe-Cr-Ni-based alloy (HK30) using the metal injection molding (MIM) process and investigated the microstructure and room·high temperature mechanical properties of the material. The effect of hot isostatic pressing (HIP) on properties was also examined. The average grain sizes were 24.1 µm for an MIM specimen and 29.1..... More

Abstract
An excellent grain-oriented electrical steel is composed of grains with exact Goss orientation. In order to produce this, it is important to control the Goss-oriented grains during the cold-rolling process. In this study, textures measured by X-ray diffraction (XRD) and electron backscatter diffraction (EBSD) were analyzed for 1, 10, and..... More

Abstract
The effects of submerged-arc welding consumables, wire and flux, on solidification cracking in the weld metal of medium-carbon steel were investigated. It showed that weld metal with a greater amount of C, S, and P had a wider brittleness temperature range, BTR, which resulted in longer total and maximum crack..... More

Abstract
Solvent extraction of La, Ce, Pr, Nd and Sm from chloride solutions was studied using PC88A and Cyanex 572 as the extractants. Our results indicated that the acidity of the aqueous solution and saponification degree had some effect on the percentage extraction of metal ions. The distribution coefficient of the..... More

Abstract
In this work, MgH₂, Mg₂Ni, and Ni were added to Mg in order to improve the hydrogen-storage properties of Mg. A 84 wt% Mg + 10 wt% MgH₂ + 5 wt% Mg₂Ni + 1 wt% Ni sample (designated the Mg-based sample) was prepared by milling under a hydrogen atmosphere in..... More

Abstract
We report the effects of interface control using reduced graphene oxide (RGO) on the thermoelectric transport properties of polycrystalline SnSe compounds. Polycrystalline SnSe-RGO composites were prepared by the consolidation of SnSe powder coated with the RGO by hot pressing, and the RGO content was controlled to be 0, 0.2, 0.5..... More
