Korean J. Met. Mater. 2020;58(3):162-168.   Published online 2020 Mar 5
DOI: https://doi.org/10.3365/KJMM.2020.58.3.162

A superelastic titanium alloy was subjected to uniaxial tensile deformation at room temperature. The microstructural evolution and deformation mechanisms of the superelastic titanium alloy were investigated by electron backscatter diffraction (EBSD) and X-ray diffraction (XRD). Multiple deformation mechanisms including stress-induced martensitic transformation (SIMT), dislocation slip, {332}<113> and {112}<111> mechanical twinning..... More

Hydrogen-Affected Tensile and Fatigue Properties of Ti-6Al-4V Sheets by Superplastic Forming
Jinil Son, Junhyuk Park, Daeho Jeong, Yongnam Kwon, Masahiro Goto, Sangshik Kim
Korean J. Met. Mater. 2017;55(9):615-623.   Published online 2017 Aug 30
DOI: https://doi.org/10.3365/KJMM.2017.55.9.615

Mill-annealed Ti-6Al-4V (Ti64) sheets were formed into rectangular shaped pans with two square recesses by the superplastic forming (SPF) technique under high pressure using commercial grade argon gas. The SPF process induced a significant decrease in the tensile ductility and high cycle fatigue (HCF) resistance of the Ti64 alloy. The..... More

High-strength Ti Alloy Prepared via Promoting Interstitial-Carbon Diffusion
침입형 탄소 확산을 이용하여 제조한 고강도 Ti 합금

Korean J. Met. Mater. 2017;55(5):342-347.   Published online 2017 May 9
DOI: https://doi.org/10.3365/KJMM.2017.55.5.342

Feasibility studies are performed to determine the suitability of a novel simple synthesis technique for fabricating a new Ti alloy with improved strength and ductility, while exhibiting lower cell toxicity. Through consolidating pure Ti powders under a C atmosphere at elevated temperatures, a bulk form of the Ti alloy, in..... More

Korean J. Met. Mater. 2017;55(1):60-66.   Published online 2017 Jan 5
DOI: https://doi.org/10.3365/KJMM.2017.55.1.60

Yttrium Aluminum Garnet (YAG) single crystal has received much attention as the high power solid-state laser’s key component in industrial and medical applications. Various growth methods have been proposed, and currently the induction-heating Czochralski (IHCZ) growth method is mainly used to grow YAG single crystal. Due to the intrinsic properties..... More

Effect of Aging Time and Temperature on Microstructure and Mechanical Properties of Ti-39Nb-6Zr Alloy
Ti-39Nb-6Zr 합금의 시효처리를 통한 미세조직 및 기계적 특성 제어
Hyun Jun Kwon, Ka Ram Lim, Yong Tae Lee, Dong Geun Lee, Jun Hee Lee, Seung Eon Kim

Korean J. Met. Mater. 2016;54(12):925-930.   Published online 2016 Dec 5
DOI: https://doi.org/10.3365/KJMM.2016.54.12.925

The aim of this study is to optimize the microstructure and mechanical properties of Ti-39Nb-6Zr (TNZ40) for bio-implant applications. TNZ40 was designed to have a low elastic modulus (~40 GPa) and good biocompatibility. However, the alloy shows relatively low strength compared to other titanium alloys for bio-implant. In the present..... More
