Enhancement of Dielectric Properties via Crystal Structure and Microstructure Control in the (K<sub>0.5</sub>Na<sub>0.5</sub>)NbO<sub>3</sub>-SrTiO<sub>3</sub> System
(K0.5Na0.5)NbO3-SrTiO3계에서 결정구조 및 미세구조 제어를 통한 유전특성 향상
Seong Eun Lee, Jun-Hyeong Kwon, Kyoung-Seok Moon
이성은, 권준형, 문경석
Korean J. Met. Mater. 2021;59(7):499-504.   Published online 2021 Jun 16
DOI: https://doi.org/10.3365/KJMM.2021.59.7.499

Abstract
Solid solutions and composites of a mixture of (K0.5Na0.5)NbO3 (KNN) and SrTiO3 (ST) were respectively synthesized by different process routes using a conventional solid state reaction. All starting materials were mixed simultaneously and calcined at 800 oC for 4 h to obtain the solid solutions of KNN-ST. Meanwhile, the composites..... More

Microstructure and Mechanical Properties of Continuous Welded 50N Rail
Wookjin Choi, Min Ji Song, Nam-Hyoung Lim, Soo Yeol Lee
Korean J. Met. Mater. 2019;57(12):755-763.   Published online 2019 Dec 5
DOI: https://doi.org/10.3365/KJMM.2019.57.12.755

Abstract
Rails are subjected to repeated stresses due to wheel-rail contact during train service. Rails under stress conditions undergo microstructural changes, and these cause degradations of the structural integrity and lifetime of rails. In this study, three different rails (newly-manufactured rail, newly-manufactured head-hardened rail, and worn (used) rail) were compared to..... More

                
Capture and Solidification of Rare Earth Nuclide (Nd) in LiCl-KCl Eutectic Salt Using a Synthetic Inorganic Composite
무기합성매질을 이용한 LiCl-KCl 공융염 내 희토류 핵종(Nd)의 포집 및 고화

Korean J. Met. Mater. 2017;55(6):419-426.   Published online 2017 Jun 1
DOI: https://doi.org/10.3365/KJMM.2017.55.6.419

Abstract
In this study, neodymium (Nd) nuclides in LiCl-KCl eutectic salts were captured and solidified using a synthetic inorganic composite (Li2O-SiO2-Al2O3-B2O3), a process that allows the selective capture of Nd and fabrication of a composite with Nd captured from waste, without additional additives or mixing. The Nd nuclides in the LiCl-KCl..... More

Korean J. Met. Mater. 2017;55(1):53-59.   Published online 2017 Jan 5
DOI: https://doi.org/10.3365/KJMM.2017.55.1.53

Abstract
The objective of this study was to obtain basic data for trapping gaseous technetium (Tc) oxide generated from the voloxidation process in spent nuclear fuel pyroprocessing. Rhenium (Re) and Ca(OH)2 were used as surrogates for the technetium and a trapping material, respectively. The trapping characteristics of rhenium oxide were investigated..... More
