Abstract
This study examined the effects of minor alloying elements (C, Ni, Cr, and Mo) on the long-term corrosion behaviors of ultrahigh-strength automotive steel sheets with a tensile strength of more than 1800 MPa. A range of experimental and analytical results showed that the addition of Ni, Cr, and Mo decreased..... More

Effects of Molybdenum on HIC Susceptibility in Normalized Pressure Vessel Steels for Sour Service Applications
Kijung Park, Dae Hyun Cho, Min-Ho Park, Cheol-Woong Yang
Korean J. Met. Mater. 2019;57(7):405-411.   Published online 2019 Jun 5
DOI: https://doi.org/10.3365/KJMM.2019.57.7.405

Abstract
This paper discusses a molybdenum-added alloy design for normalized pressure vessel steels, to reduce hydrogen induced cracking (HIC) and inhibit crack propagation. The change in microstructure produced by the modified alloy composition was analyzed to determine its effect on HIC characteristics. The microstructural change was observed by optical microscopy, hardness..... More

Study on the Water Durability of Molybdate Glasses with B<sub>2</sub>O<sub>3</sub> as Low Temperature Sealing Materials
Jae-Young Shin, Jae-Min Cha, Dae-Sung Kim, Dea-Geol Jeong, Jun-Hyeon Bae, Bong-Ki Ryu
Korean J. Met. Mater. 2017;55(12):905-910.   Published online 2017 Dec 4
DOI: https://doi.org/10.3365/KJMM.2017.55.12.905

Abstract
The boron alkali molybdate glass system was investigated as lead-free low-temperature melting sealing materials, with different boron oxide contents between 0 and 8 mol%. The glasses were characterized using X-ray diffraction (XRD), differential scanning calorimetry (DSC), infrared spectroscopy (IR), and by densities. Their chemical properties were measured by their dissolution..... More
