Korean J. Met. Mater.
;59(2):113-120. Published online 2021 Jan 27
DOI:
https://doi.org/10.3365/KJMM.2021.59.2.113
Abstract
Ti has excellent properties but is more expensive than other materials due to its high melting point, high reactivity and difficult processability. One way to lower the production cost of Ti products is to recycle Ti scraps. Before recycling Ti scraps, pretreatment to remove contamination is essential. Ti scraps can.....

DOI:
https://doi.org/10.3365/KJMM.2019.57.10.617
Abstract
In the present study, new Mg-based bulk metallic glasses have been developed in a Mg-Cu-GdNd based system using a Mg-Nd byproduct obtained from the recycling process of NdFeB magnet scrap through liquid metal extraction. The Mg-Cu-Gd-Nd bulk metallic glasses with a diameter of 2 mm are fabricated by injection casting.....

DOI:
https://doi.org/10.3365/KJMM.2019.57.9.569
Abstract
In this study, an eco-friendly pretreatment process was developed to recycle titanium turning scraps and ferro-titanium ingots with low gaseous impurities were prepared using recycled titanium turning scraps. The amount of gaseous impurities of titanium scraps before removing the machining oils on the surface was as high as 20000 ppm......

DOI:
https://doi.org/10.3365/KJMM.2018.56.7.511
Abstract
The leaching behavior of silver from electronic scrap using acidic thiourea solution was studied. The results showed that the silver leaching percentage was affected by the concentration of thiourea and hydrochloric acid, the oxidant such as ferric ions, solid-liquid ratio, temperature, rpm, etc. The leaching percentage of silver decreased with.....
