Effect of Molybdenum on the Mechanical and Corrosion Properties of Ti-xMo-2Fe Beta Alloys
Ti-xMo-2Fe 베타계 타이타늄 합금의 기계적 특성 및 부식 특성에 미치는 Mo의 영향 평가
Jeong-Yeon Park, Jae-Gwan Lee, Yong-Jae Lee, Dong-Geun Lee
박정연, 이재관, 이용재, 이동근
Korean J. Met. Mater. 2024;62(2):125-131.   Published online 2024 Jan 30
DOI: https://doi.org/10.3365/KJMM.2024.62.2.125

Abstract
Titanium alloys are currently used in offshore industries. The titanium alloys used in offshore plants need to have excellent corrosion resistance and mechanical properties because offshore plants are exposed to harsh corrosive environments. At this time, the Ti-6Al-4V ELI alloy is mainly used in offshore plants because it has excellent..... More

Korean J. Met. Mater. 2023;61(10):741-747.   Published online 2023 Sep 25
DOI: https://doi.org/10.3365/KJMM.2023.61.10.741

Abstract
The addition of expensive elements to β titanium alloys, which are widely used in the aerospace and automobile industries, causes their price to increase. Low-cost, high-strength alloy (Ti-12.1Mo-1.0Fe) was designed in this study and the compressive behaviors of this alloy were evaluated for application to automobile parts, etc. As a.....

Microstructural Evolution and Mechanical Properties According to Aging Conditions of Ti-5Mo-2Fe Alloy
Ti-5Mo-2Fe 합금의 시효처리 조건에 따른 미세조직 변화 및 기계적 특성
Hong-Min Kim, Se-Yeong Park, Dong-Geun Lee
김홍민, 박세영, 이동근
Korean J. Met. Mater. 2023;61(8):545-552.   Published online 2023 Jul 20
DOI: https://doi.org/10.3365/KJMM.2023.61.8.545

Abstract
Beta-type titanium alloys have a low elastic modulus, excellent cold workability, and are widely used as implant materials. High strength is possible by forming a precipitation in the β-matrix via solution treatment and aging treatment. However, beta titanium alloys require a large amount of beta-stabilizing elements (Fe, Nb, Mo, Ta,..... More

Korean J. Met. Mater. 2020;58(7):501-506.   Published online 2020 Jul 5
DOI: https://doi.org/10.3365/KJMM.2020.58.7.501

Abstract
The properties and H2O adsorption characteristics of two types of zeolites (3A and 13X) with the same shape but different element composition were identified. These zeolites are used in gas purification processes to manufacture 9N ultra-pure inert gases for semiconductor process applications. To analyze the shape and microstructure of the.....

Korean J. Met. Mater. 2017;55(7):453-459.   Published online 2017 Jul 4
DOI: https://doi.org/10.3365/KJMM.2017.55.7.453

Abstract
Extensive studies of the metastable structures in beta Ti alloys have investigated the ambiguity of the unstable phase. Their microstructural characteristics have been observed to have a modulated structure, and spot satellites of diffraction in TEM, however the formation mechanisms have not been successfully interpreted because of the resolution limit.....

Korean J. Met. Mater. 2017;55(5):363-371.   Published online 2017 May 9
DOI: https://doi.org/10.3365/KJMM.2017.55.5.363
Abstract
The effects of the annealing temperature on the microstructure and tensile properties of cold-rolled light-weight steels are investigated using two Fe-30Mn-xAl-0.9C alloys that contain different Al content. The initial alloy microstructure is composed of a single austenite or a mixture of austenite and ferrite depending on the nominal aluminum content.... More
