Myong-Soo Lee, Kwon-Hoo Kim, Chang-Yong Kang
이명수, 김권후, 강창룡
Korean J. Met. Mater. 2019;57(2):71-76.   Published online 2019 Jan 8
DOI: https://doi.org/10.3365/KJMM.2019.57.2.71

Abstract
This study was carried out to investigate the effect of fatigue stress magnitude on the tensile properties of the damaged Fe – 22Mn – 12Cr – 3Ni – 2Si – 4Co damping alloy under various fatigue stress magnitudes. α´ and ε-martensite were formed by fatigue stress in the Fe –.....

Korean J. Met. Mater. 2018;56(7):499-504.   Published online 2018 Jul 5
DOI: https://doi.org/10.3365/KJMM.2018.56.7.499

Abstract
This study investigated the effect of Si on the characteristics of FCA multi-layer weld metal with 460 MPa yield strength grade steels for ships and marine structures. The effect on microstructure was evaluated by tensile, charpy impact and CTOD testing of 4 FCAW welds containing various C and Si contents...... More

Effect of Thermo-mechanical Treatment on the Formation Behavior of Martensite in 316L Stainless Steel
316L 스테인리스강에서 마르텐사이트 생성거동에 미치는 가공열처리의 영향
Jong-Sig Kim, Jae-Nam Kim, Chang-Yong Kang
김종식, 김재남, 강창룡
Korean J. Met. Mater. 2018;56(4):265-271.   Published online 2018 Apr 5
DOI: https://doi.org/10.3365/KJMM.2018.56.4.265

Abstract
This study was carried out to investigate the effect of thermo-mechanical treatment on the formation behavior of martensite in 316L stainless steel. Dislocation, α' and ε-martensite were formed by thermo-mechanical treatment. Martensite with surface relief and specific direction was formed by thermo-mechanical treatment. Martensite formed by thermo-mechanical treatment were reversed..... More
