Korean J. Met. Mater. 2024;62(12):972-980.   Published online 2024 Nov 29
DOI: https://doi.org/10.3365/KJMM.2024.62.12.972

Abstract
This study investigates the thermoelectric properties of Fe1-xCoxSe2 (x = 0, 0.25, 0.5, 0.75, and 1) alloys using theoretical modeling approaches. The Single Parabolic Band (SPB) model was employed to calculate band parameters such as density-of-states effective mass (md*), non-degenerate mobility (μ0), weighted mobility (μw), and B-factor. As the alloying..... More

                
Effect of Zn-Doping on the Phase Transition Behavior and Thermoelectric Transport Properties of Cu<sub>2</sub>Se

Korean J. Met. Mater. 2020;58(7):466-471.   Published online 2020 Jul 5
DOI: https://doi.org/10.3365/KJMM.2020.58.7.466

Abstract
We report on the phase transition behavior and thermoelectric transport properties of Zn-doped Cu2Se. Cu2Se is comprised of nontoxic, low-cost and abundant elements, and has been attracting attention because of its very high thermoelectric performance, ZT, at high temperatures. Many studies have reported enhanced ZT in impurity doped Cu2Se, however,..... More

Simulation and Experimental Study on the Steady Conduction Solution for Continuous Rheo-Casting for A356 Alloy
Do Minh Duc, Nguyen Hong Hai, Pham Quang
Korean J. Met. Mater. 2017;55(3):202-208.   Published online 2017 Mar 3
DOI: https://doi.org/10.3365/KJMM.2017.55.3.202

Abstract
Computational fluid dynamic modeling of a continuous rheo-casting technology was conducted, consistent with the manufacturing of 3 mm-thin plates made of aluminum alloy A356. The A numerical simulation on of the stabilizing time of the material crystallization was carried out using the ANSYS FLUENT code. Solidification and melting models were..... More
