Korean J. Met. Mater. 2022;60(11):811-818.   Published online 2022 Oct 31
DOI: https://doi.org/10.3365/KJMM.2022.60.11.811

Abstract
The strain aging and hydrogen embrittlement behavior of two bake hardening (BH) steels with different microstructures were investigated in this study. The single-phase BH steel was composed of fully ferrite, while the dual-phase BH steel consisted of ferrite and 3 % martensite. The BH index and aging index (AI) of..... More

Korean J. Met. Mater. 2022;60(2):102-113.   Published online 2022 Jan 12
DOI: https://doi.org/10.3365/KJMM.2022.60.2.102

Abstract
The aim of this study was to investigate the effect of precipitates and cold working on the reheat cracking of STS 347 austenitic stainless steel. Three different heat treatments to form NbC and M23C6 precipitates were applied to the STS 347 austenitic stainless steel and 10% pre-strain was additionally introduced..... More

Korean J. Met. Mater. 2020;58(11):752-758.   Published online 2020 Oct 15
DOI: https://doi.org/10.3365/KJMM.2020.58.11.752

Abstract
The effect of pre-strain on the hydrogen embrittlement of Nb-free and Nb-added low-carbon steels with ferrite-pearlite structure was investigated in this study. After the steels were electrochemically charged with hydrogen, slow-strain rate tensile (SSRT) tests were conducted on them to examine hydrogen embrittlement behavior. The SSRT test results revealed that..... More
