Effects of Two-Step Anodization on Surface Wettability in Surface Treatment of Aluminum Alloy
알루미늄 합금의 표면처리에 있어서 2단계 양극산화의 젖음성 영향
Jae Dong Eo, Jingyu Kim, Yongsug Jung, Jong-Hang Lee, Wook Bae Kim
어재동, 김진규, 정용석, 이종항, 김욱배
Korean J. Met. Mater. ;59(2):73-80.   Published online 2021 Jan 27
DOI: https://doi.org/10.3365/KJMM.2021.59.2.73

Industrial anodizing of aluminum alloys is widely employed for various products, to improve corrosion and contamination protection as well as aesthetic appearance. At the same time, nanostructure fabrication using highly ordered porous aluminum oxides has been increasingly investigated in academic research for diverse micro-/nano applications. This approach is based on..... More

Investigation of Structure-Property Relations in Porous Metals Using Finite Element Simulation
유한요소해석을 활용한 다공 금속의 구조-물성 관계 연구
Dongmyung Jung, Yongwoo Kwon
정동명, 권용우
Korean J. Met. Mater. 2019;57(11):747-754.   Published online 2019 Nov 5
DOI: https://doi.org/10.3365/KJMM.2019.57.11.747

A porous material can be regarded as a mixture of pores and solid phases, with effective thermal and mechanical properties that significantly differ from those of its base material. Material effective properties depend greatly on the structure and porosity. The effective properties of materials with different pore structures can vary..... 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

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
