Korean J. Met. Mater. 2018;56(2):103-112.   Published online 2018 Feb 5
DOI: https://doi.org/10.3365/KJMM.2018.56.2.103

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 mVSCE for..... More

Korean J. Met. Mater. 2017;55(8):566-571.   Published online 2017 Aug 1
DOI: https://doi.org/10.3365/KJMM.2017.55.8.566

The Paris climate change agreement made a commitment to keep global warming below 2 ℃. The Korean government confirmed that it would seek a 37% reduction in CO2 emissions by 2030 from the Business As Usual level. CO2 emissions from Korean iron and steel industries account for approximately 15.4% of..... More

Capture and Solidification of Rare Earth Nuclide (Nd) in LiCl-KCl Eutectic Salt Using a Synthetic Inorganic Composite

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

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

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

Korean J. Met. Mater. 2016;54(11):846-854.   Published online 2016 Nov 5
DOI: https://doi.org/10.3365/KJMM.2016.54.11.846

The world is gradually running short of high quality iron resources. This forces ironmaking processes to focus on the use of low quality iron ores. Carbon composite iron oxide briquettes (CCB) are one of the alternative choices. CCB enables the utilization of low quality powdered iron ores and coal, and..... More
