Korean J. Met. Mater. 2019;57(9):569-574.   Published online 2019 Aug 21
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...... More

Abstract
In the present study, new Mg-based bulk metallic glasses have been developed in a Mg-Cu-Gd-Nd 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... More
