Korean J. Met. Mater. 2023;61(3):213-217.   Published online 2023 Feb 24
DOI: https://doi.org/10.3365/KJMM.2023.61.3.213

Abstract
Herein we report the optimized processing conditions of hot extrusion for fabricating an n-type Bi2Te2.7Se0.3 thermoelectric compound, with high electronic transport properties as well as improved mechanical reliability. We fabricated a Bi2Te2.7Se0.3 extrudate that was 3.8 mm in diameter and 700 mm in length by controlling the processing parameters of..... More

                
Effects of Charge Compensation on the Thermoelectric Properties of (La1-zCez)0.8Fe4-xCoxSb12 Skutterudites
Kyung-Wook Jang, Ye-Eun Cha, Deok-Yeong Choi, Sunuk Kim, Won-Seon Seo, Kyu Hyoung Lee, Il-Ho Kim
Korean J. Met. Mater. 2021;59(4):239-246.   Published online 2021 Mar 24
DOI: https://doi.org/10.3365/KJMM.2021.59.4.239

Abstract
La/Ce-partially double-filled and Co-charge-compensated (La1−zCez)0.8Fe4−xCoxSb12 skutterudites were synthesized, and their thermoelectric properties were studied by varying the filling ratio and charge compensation. X-ray diffraction analysis revealed that the matrix phase was skutterudite and a secondary phase was determined to the marcasite FeSb2. However, the formation of marcasite could be inhibited.....

Extended Energy Conservation Law in Alloys: the Absence of Energy Non-Equilibrium
Myung Sik Choi, Han Gil Na, Changhyun Jin, Kyu Hyoung Lee
Korean J. Met. Mater. 2020;58(8):566-572.   Published online 2020 Jul 27
DOI: https://doi.org/10.3365/KJMM.2020.58.8.566

Abstract
Assuming that many of the materials produced in a non-equilibrium state remain unchanged, an extended space–energy conservation law was proposed based on the existing energy conservation law. In the present study, by analyzing the well developed equilibrium binary phase diagram of iron (Fe) – carbon (C), we show that energy..... More
