Korean J. Met. Mater. 2017;55(8):559-565. Published online 2017 Aug 1
DOI: https://doi.org/10.3365/KJMM.2017.55.8.559

Abstract
Spent nuclear fuel is stored and transported in cask bodies, but they become embrittled with the passage of time resulting in lattice defects due to neutron irradiation. Cask bodies made by the quenching and tempering (QT) treatment are not safe and are hard to store because of embrittlement caused by..... More

Korean J. Met. Mater. 2016;54(8):585-591. Published online 2016 Aug 5
DOI: https://doi.org/10.3365/KJMM.2016.54.8.585

Abstract
Overlay welding technique is one of methods used to improve metal mechanical properties such as strength, toughness and corrosion resistance. Generally, Inconel 625 alloy is used for overlay welding layer on low carbon steels for economic consideration. However, the method produces some problems in the microstructure of the cast structure... More
