Abstract
In this study, the effects of rolling temperature on the microstructural characteristics of a highspeed-rolled Mg alloy with a non-basal texture were investigated. To this end, commercial AZ31 alloy samples in which the basal poles of most grains were tilted at an angle of 45° from the normal direction (ND)..... More

                        
Hydrogen Storage Properties of Mg-Graphene Composites
Myoung Youp Song, Young Jun Kwak, Eunho Choi
Korean J. Met. Mater. 2018;56(7):524-531.   Published online 2018 Jul 5
DOI: https://doi.org/10.3365/KJMM.2018.56.7.524

Abstract
To improve the hydrogen uptake and release properties of magnesium (Mg), five weight percent of graphene was added to pre-milled Mg by milling in hydrogen (reaction-involving milling). The hydrogen uptake and release properties of the graphene-added Mg (named Mg-5graphene) were investigated. Premilling of Mg (for 24 h) and then adding..... More

Korean J. Met. Mater. 2018;56(4):327-333.   Published online 2018 Apr 5
DOI: https://doi.org/10.3365/KJMM.2018.56.4.327

Abstract
Traditional organic binders used by the foundry industry produce problems such as generation of volatile organic compounds(VOCs), smoke and etc. A water glass binder system has been developed to improve the casting strength and to solve the environmental problems. However the water glass binder has a serious problem of sand..... More

      
Hydrogen Sorption of Pure Mg and Niobium (V) Fluoride-Added Mg Alloys Prepared by Planetary Ball Milling in Hydrogen
Hye Ryoung Park, Young Jun Kwak, Seong Ho Lee, Myoung Youp Song
Korean J. Met. Mater. 2016;54(12):916-924.   Published online 2016 Dec 5
DOI: https://doi.org/10.3365/KJMM.2016.54.12.916

Abstract
In this work, niobium (V) fluoride was selected as an additive to heighten the hydrogen sorption rates of Mg. Specimens of pure Mg, 5 wt% niobium fluoride-added Mg, and 10 wt% niobium fluoride-added Mg were prepared by planetary ball milling in hydrogen. The hydrogen sorption properties of the specimens were..... More
