Corrosion Behavior of SLMed Ti6Al4V-Equine Bone Nanocomposites
Se Hee Kim, Se Eun Shin
Korean J. Met. Mater. 2024;62(11):837-843.   Published online 2024 Nov 5
DOI: https://doi.org/10.3365/KJMM.2024.62.11.837

Abstract
Ti6Al4V is one of the most widely used Ti alloys in biomedical applications, such as orthopedic and dental implants, due to its excellent mechanical properties, biocompatibility, and high corrosion resistance. Metal implants require high bonding strength between the implant and bone for long-term use in the human body; Hydroxyapatite (HAp)..... More

                
Investigation on the Structural and Mechanical Properties of Al Foam Manufactured by Spark Plasma Sintering and Compression Molding Methods
방전 플라즈마 소결과 압축 성형 방법으로 제조된 알루미늄 다공체의 구조적, 기계적 특성 연구
Seunghyeok Choi, Sang-Hwa Lee, Jae-Gil Jung, Seok-Jae Lee, Tae-Young Ahn, Yu-Song Choi, Seung Bae Son
최승혁, 이상화, 정재길, 이석재, 안태영, 최유송, 손승배
Korean J. Met. Mater. 2024;62(7):533-541.   Published online 2024 Jun 28
DOI: https://doi.org/10.3365/KJMM.2024.62.7.533
Abstract
Metal foam materials are used for various purposes including electrode materials, catalyst filters, and gas diffusion filters due to their porous structure. Increasing demand for metal foams has generated research to increase porosity as well as produce different pore sizes. The present paper illustrates a comparison of open-cell aluminum foams... More

Friction and Wear Behavior of Selective Laser Melted Ti6Al4V-Equine Bone Nanocomposites
선택적 레이저 용융 Ti6Al4V-Equine Bone 나노 복합재료의 마찰 및 마모 특성
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
