Pressure Transmission in the Compaction Process of Nickel Powder Using the Finite Element Methods
Jong Won Baek, Seong Jin Park
Korean J. Met. Mater. 2019;57(2):115-123.   Published online 2019 Jan 9
DOI: https://doi.org/10.3365/KJMM.2019.57.2.115

Abstract
The compression process is one of the more widely used industrial manufacturing methods for fabricating desired shape of specimens with various materials such as metals and ceramics. In the compaction process, the upper punch moves into the powder, and force is transmitted between particles, then achieving densification. In this process,..... More

                        
Analysis of a Slab and Slab Heater Cover in a Compact Endless Cast and Rolling Mill Process Using Finite Element Methods
Jong Won Baek, Joo Won Oh, Jae-Sook Chung, Yong-Seok Cho, Seong Jin Park
백종원, 오주원, 정제숙, 조용석, 박성진
Korean J. Met. Mater. 2019;57(1):43-50.   Published online 2018 Dec 14
DOI: https://doi.org/10.3365/KJMM.2019.57.1.43

Abstract
Compact Endless cast and rolling Mill (CEM) processes were developed and used to fabricate steel products such as steel slabs. However, the coiling furnace in this process was very expensive, so a new layout was suggested. As the coiling furnace was removed, the interval among the slab heaters had to.....

Material Characterization of Single Crystalline Cu Subjected to High Strain Rates and High Temperatures for Multiscale Simulation
Yujin Seong, Youngkyu Kim, Im Doo Jung, Sungho Kim, See Jo Kim, Seong-Gon Kim, Hak Jun Kim, Seong Jin Park
Korean J. Met. Mater. 2017;55(11):760-767.   Published online 2017 Oct 31
DOI: https://doi.org/10.3365/KJMM.2017.55.11.760

Abstract
The material characterization of single crystalline Cu columns was numerically carried out at the submicroscopic level. A molecular dynamics (MD) simulation was employed using the embedded-atom method (EAM) interatomic potential between a pair of Cu atoms to describe the interactions among Cu atoms. First, the relationship between mechanical properties and..... More

Experimental and Simulation Analysis of Hot Isostatic Pressing of Gas Atomized Stainless Steel 316L Powder Compacts
Dongguo Lin, Sangyul Ha, Youngho Shin, Dong Yong Park, Seong Jin Park, Sung Taek Chung, Ravi Bollina, Seongkyu See
Korean J. Met. Mater. 2016;54(10):732-742.   Published online 2016 Oct 5
DOI: https://doi.org/10.3365/KJMM.2016.54.10.732

Abstract
In this work, both experimental and numerical studies were conducted to investigate the densification behavior of stainless steel 316L (STS 316L) powders during hot isostatic pressing (HIP), and to characterize the mechanical properties of HIPed specimens. The HIP experiments were conducted with gas atomized STS 316L powders with spherical particle..... More
