Youngdae Kim, Yinsheng He, Jiye Bang, Jinesung Jung
김영대, 하인생, 방지예, 정진성
Korean J. Met. Mater. 2022;60(11):865-871.   Published online 2022 Oct 31
DOI: https://doi.org/10.3365/KJMM.2022.60.11.865

Abstract
A gas turbine (GT) blade is a key hot-pass component for advanced GT engines, and should have stable properties under extreme conditions of 1,350°C and 3,600rpm, etc. The GT blade, after operating with nearly 800 equivalent start-stops (ES) or 24,000 equivalent operation hours (EOH), should be replaced due to degradation.....

Korean J. Met. Mater. 2021;59(10):698-708.   Published online 2021 Sep 6
DOI: https://doi.org/10.3365/KJMM.2021.59.10.698

Abstract
The metallurgical aspects of weld solidification cracking in Ni-based superalloys (with Ti+Al > 5 mass%) have not been widely investigated thus far. Herein, the solidification cracking susceptibility of the CM247LC superalloy and its welds with ERNiFeCr-2 filler wire was quantitatively evaluated using a novel modified Varestraint testing method, for the.....

Korean J. Met. Mater. 2019;57(7):468-474.   Published online 2019 Jun 5
DOI: https://doi.org/10.3365/KJMM.2019.57.7.468

Abstract
The evolution of microstructure and mechanical characteristics during the rejuvenation of a hot gas pass component of a gas turbine was investigated with an actual service-exposed bucket in a power plant. Heat treatment and hot isostatic pressing processes were conducted to rejuvenate a hot gas pass component of a F..... More
