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.....

Yeon kwan Kang, Yinsheng He, Han-Sang Lee, Beom-Soo Kim, Liming Xu, Keesam Shin
Korean J. Met. Mater. 2019;57(12):817-827.   Published online 2019 Nov 22
DOI: https://doi.org/10.3365/KJMM.2019.57.12.817

Abstract
The use of locally developed high performance alloys in power plants has become essential in the past ten years. Application of these alloys has been difficult because of a shortage of field demonstration testing, and the lack of lab-based test data. In this work, three types of locally developed heat.....
