Se-Hee Kim, Su-Hyun Bae, Sang-Bae Park, Hoon Seonwoo, Se-Eun Shin
김세희, 배수현, 박상배, 선우훈, 신세은
Korean J. Met. Mater. 2024;62(5):351-359.   Published online 2024 May 5
DOI: https://doi.org/10.3365/KJMM.2024.62.5.351

Abstract
Ti6Al4V is commonly used in implants because of its excellent mechanical properties, corrosion resistance, and biocompatibility. While Hydroxyapatite (HAp) is typically used for strong biological bonding between Ti6Al4V implants and bone tissue, this study takes a different approach by incorporating Equine Bone (EB), which has a chemical structure similar to.....

Analysis of Precipitation Phase of Alloy1.4957 Heat-Resistant Steel for Gasoline Turbocharger
가솔린 터보차저용 Alloy1.4957 내열강의 석출 상 분석
Jong-Kwan Lee, Byeong-Joo Lee, Eon-Sik Lee
이종관, 이병주, 이언식
Korean J. Met. Mater. 2023;61(10):721-728.   Published online 2023 Sep 25
DOI: https://doi.org/10.3365/KJMM.2023.61.10.721

Abstract
Recently, strengthened environmental regulations have required the downsizing of gasoline engines, and as a result, demand for gasoline turbochargers has rapidly increased. The vane of a turbocharger controls the flow of gases toward the turbine, and it is manufactured by powder metallurgy due to its complex shape. Gasoline engines have..... More

                
A Study on the Variation in Tensile Ductility of Porous Sintered Iron
다공성 소결 순철에서 인장연성의 변화에 관한 연구
Jae-Young Jung, Ho-Sang Sohn
정재영, 손호상
Korean J. Met. Mater. 2018;56(1):34-39.   Published online 2018 Jan 1
DOI: https://doi.org/10.3365/KJMM.2018.56.1.34

Abstract
A model based on Irwin's approach to elastic-plastic deformation was applied to predict the tensile ductility of a sintered iron. The evaluation of this model using experimental results for porous sintered iron showed that tensile ductility depends not only on the pore volume fraction, but also the pore size and..... More

    
High-strength Ti Alloy Prepared via Promoting Interstitial-Carbon Diffusion
침입형 탄소 확산을 이용하여 제조한 고강도 Ti 합금
Bo-Young Kim, Se-Hyun Ko, Jae-Chul Lee
김보영, 고세현, 이재철
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

Abstract
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
