Ni-Cr-Mo-V steel alloys for high-speed railway brake discs were prepared to investigate the effect of alloying element contents on the microstructure and mechanical properties. The Cr, Mo, Mn alloying elements were incorporated into the steel alloys, which contained low carbon content in the range 0.16 wt.% ~ 0.21 wt.% to..... More

AISI 304 Steel Brazing Using A Flexible Brazing Foil Fabricated by Tape Casting Method
Ashutosh Sharma, Soon-Jae Lee, Joo-Hee Oh, Jae Pil Jung
Korean J. Met. Mater. 2017;55(12):836-844.   Published online 2017 Dec 4
DOI: https://doi.org/10.3365/KJMM.2017.55.12.836

The authors report the fabrication of a flexible nickel brazing foil using powdered nickel alloy filler (BNi-2) mixed with an organic binder. The organic binder was composed of a polyacrylic acid polymer, glycol, carbon tetrachloride, and water as a dispersion medium for the powder. The brazing paste so formed was..... More

Increase in the Hydrogen-Sorption Rates and the Hydrogen-Storage Capacity of MgH<sub>2</sub> by Adding a Small Proportion of Zn(BH<sub>4</sub>)<sub>2</sub>
Hye Ryoung Park, Young Jun Kwak, Myoung Youp Song
Korean J. Met. Mater. 2017;55(9):657-663.   Published online 2017 Aug 30
DOI: https://doi.org/10.3365/KJMM.2017.55.9.657

Abstract: In this work, Zn(BH4)2 was added to improve the hydrogen-storage properties of MgH2. A 99 wt% MgH2+1 wt% Zn(BH4)2 sample was prepared by milling in a planetary ball mill in a hydrogen atmosphere. The proportion of the added Zn(BH4)2 was small (1 wt%) in order to increase hydriding and..... More

Material Analysis & Characterization
Study of Water Resistance of Fe<sub>2</sub>O<sub>3</sub> Doped P<sub>2</sub>O<sub>5</sub>ZnOBi<sub>2</sub>O<sub>3</sub> Sealing Glass System
Moon Kyung Hwang, Il Gu Kim, Bong Ki Ryu
Korean J. Met. Mater. 2016;54(8):621-625.   Published online 2016 Aug 5
DOI: https://doi.org/10.3365/KJMM.2016.54.8.621

In order to strengthen the structure of the glass and ultimately improve its water resistance, P2O5–ZnO–Bi2O3 was doped with Fe2O3, which generated Fe ions in the phosphate-based glass. These ions constitute (P2O7)−4 groups within the glass network. Structural analysis using Fourier transfer infrared spectroscopy indicated that P-O-P and Bi-O-P bonds..... More
