Korean J. Met. Mater.
2024;62(12):996-1005. Published online 2024 Nov 29
DOI:
https://doi.org/10.3365/KJMM.2024.62.12.996
Abstract
The purpose of this study is to analyze the components and observe the microstructure of 98 bronze vessels excavated from the Korean Peninsula, where such vessels were widely used, to identify the alloy composition and manufacturing process of bronze artifacts by period. In addition, we attempted to confirm the changing.....

2021;59(9):624-639. Published online 2021 Aug 4
DOI:
https://doi.org/10.3365/KJMM.2021.59.9.624
Abstract
The effect of 3 forging routes (
Route A
- 1~12 passes by plane forging (PF) and reverse-plane forging (R-PF),
Route B
– 1~6 passes by PF and R-PF, 7~12 passes by diagonal forging (DF) and reversediagonal forging (R-DF),
Route C
– 1~12 passes by DF and R-DF) on maximum load.....

2019;57(1):18-27. Published online 2018 Dec 14
DOI:
https://doi.org/10.3365/KJMM.2019.57.1.18
Abstract
The effect that forging routes (3 routes, A-C) exert on the development of deformation heterogeneity in AA1100 was theoretically performed using finite element analysis. Route A corresponded to a forging process that involved from 1 to 6 passes through multi-axial diagonal forging (MADF); Route B corresponded to a forging process.....

DOI:
https://doi.org/10.3365/KJMM.2017.55.9.609
Abstract
A new Ni based superalloy with high fatigue resistance and fine grain was considered as a material for high-pressure buckets in fossil fuel power plants. Since such buckets are usually exposed to extreme operating conditions, low cycle fatigue tests were conducted to understand the microstructure evolution of the material during.....

DOI:
https://doi.org/10.3365/KJMM.2017.55.7.486
Abstract
A new Ni based superalloy is considered as bucket material because of high fatigue resistance with fine grain. However a bucket is usually exposed to high temperature for a long time, so creep rupture tests were conducted to understand the microstructure evolution during creep deformation under various stresses at temperatures.....
