Korean J. Met. Mater. 2020;58(10):660-671.   Published online 2020 Oct 5
DOI: https://doi.org/10.3365/KJMM.2020.58.10.660

Abstract
Fe-Mn-Si based shape memory alloy is a new functional material that can be used to apply prestress to civil and structural components such as concrete structures. In this study, the effects of alloying elements Ni, C and Ti on the mechanical and shape memory properties of the alloy were investigated..... More

                        
Anisotropy in Green Body Bending Strength due to Additive Direction in the Binder-Jetting Additive Manufacturing Process
Ji-Won Oh, Sahn Nahm, Byoungmoon Kim, Hanshin Choi
Korean J. Met. Mater. 2019;57(4):227-235.   Published online 2019 Apr 5
DOI: https://doi.org/10.3365/KJMM.2019.57.4.227

Abstract
The additive manufacturing (AM) process is a production technology process that has recently attracted attention. Among AM processes, the binder jetting (BJ) method is advantageous because it allows both wide material selection and design freedom. However, the output arrangement, which determines the direction in which the binder is injected during..... More

박세계, 백응률, 박노근
Korean J. Met. Mater. 2018;56(3):210-220.   Published online 2018 Mar 6
DOI: https://doi.org/10.3365/KJMM.2018.56.3.210

Abstract
Material parameters, extracted from mechanical behavior in a uniaxial direction without considering anisotropy in the rolling direction, are commonly used when doing forming analysis. However, when these material parameters are used for the forming analysis of a material which has large anisotropy, inaccurate analysis results can be obtained. In this..... More

      
Effects of Induction Heat Bending and Heat Treatment on the Boric Acid Corrosion of Low Alloy Steel Pipe for Nuclear Power Plants
Ki-Tae Kim, Min-Chul Shin, Hyun-Young Chang, Heung-Bae Park, Gi-Ho Sung, Young-Sik Kim
Korean J. Met. Mater. 2016;54(11):817-825.   Published online 2016 Nov 5
DOI: https://doi.org/10.3365/KJMM.2016.54.11.817
Abstract
In many plants, including nuclear power plants, pipelines are composed of numerous fittings such as elbows. When plants use these fittings, welding points need to be increased, and the number of inspections also then increases. As an alternative to welding, the pipe bending process forms bent pipe by applying strain... More
