Abstract
In this study, solidification cracking behavior and susceptibility in dissimilar cladding of Inconel alloy FM 52, 308L stainless steel to carbon steel, was investigated by submerged arc welding and transverse−Varestraint testing with gas tungsten arc welding. The effect of cladding conditions on cracking behavior and susceptibility was extensively evaluated, and..... More

Korean J. Met. Mater. 2018;56(8):589-596.   Published online 2018 Aug 5
DOI: https://doi.org/10.3365/KJMM.2018.56.8.589

Abstract
Martensitic 10Cr1MoW steels are widely used for high temperature components in turbine engines because they have good mechanical properties and corrosion resistance. Delta-ferrite can form locally in large ingots and the ferrite phase degrades the metal’s high-temperature properties. To decrease the fraction of delta-ferrite the solidification process should be controlled...... More

Korean J. Met. Mater. 2017;55(12):896-904.   Published online 2017 Dec 4
DOI: https://doi.org/10.3365/KJMM.2017.55.12.896

Abstract
In the iron ore sintering process, a thermal imbalance can occur in the sinter feed bed which degrades the quality of the sintered ores. In order to solve this thermal imbalance, it is necessary to control the sizes of the sintering feed charging through the chute by designing an appropriate..... More

DOI: https://doi.org/10.3365/KJMM.2017.55.3.184

Abstract
In case of the uranium (U) and zirconium (Zr) powders which have been utilized for the production of a metallic fuel in the various nuclear applications, the homogenous distribution of U powders in the Zr-U pellet has influenced significantly on the nuclear fuel performance. The inhomogeneity in a powder process..... More

DOI: https://doi.org/10.3365/KJMM.2016.54.9.659

Abstract
As a first step to optimizing the homogenization heat treatment following high temperature upset forging, the solidification segregation and the homogenization behaviors of solute elements were quantitatively analyzed for 1Cr-1.25Mo-0.25V steel ingot by electron probe micro-analysis (EPMA). The random sampling approach, which was designed to generate continuous compositional profiles of..... More
