Korean J. Met. Mater. 2018;56(1):14-25.   Published online 2018 Jan 1
DOI: https://doi.org/10.3365/KJMM.2018.56.1.14

Abstract
High entropy alloys (HEAs) are a relatively new class of metallic materials. HEAs lead to high mixing entropy and the formation of a simple solid solution rather than intermediate phases. This might be explained by the fact that the configurational entropy outweighs the enthalpy of formation of intermetallic compounds. Meanwhile,..... More

Korean J. Met. Mater. 2017;55(6):446-452.   Published online 2017 Jun 1
DOI: https://doi.org/10.3365/KJMM.2017.55.6.446

Abstract
The thermal properties of two-layered materials composed of a polymer layer embedded with dielectric AlN particles (AlN composite) coated on top of an aluminum (Al) substrate were investigated by light flash analysis (LFA). The thermal conductivity of the specimens was measured as a function of the AlN composite volume fraction..... More

Effect of Configurational Entropy of Mixing on Thermophysical Properties in Single Phase FCC Solid Solutions with Multi-Principal Elements
혼합엔트로피 제어에 따른 단일 FCC 고용체 합금의 물성변화 분석

이제인, 오현석, 김준혁, 박은수
Korean J. Met. Mater. 2017;55(1):1-9.   Published online 2017 Jan 5
DOI: https://doi.org/10.3365/KJMM.2017.55.1.1

Abstract
In the present study, we systematically investigated the effect of entropy of mixing (ΔSmix) on the mechanical and thermal properties of single phase FCC solid solutions with multi-principal elements. An increase in ΔSmix led to an increase in micro-hardness and a decrease in thermal conductivity (κ) due to severe lattice..... More
