Effects of Si and Sn Contents and Heat-Treatment Temperature on the Corrosion Behavior of AISI 439 Ferrite Stainless Steel
Chan Yang Kim, Do hyung Kim, Won sub Chung
Korean J. Met. Mater. 2022;60(1):26-34.   Published online 2021 Dec 10
DOI: https://doi.org/10.3365/KJMM.2022.60.1.26

Abstract
This study was conducted to evaluate the corrosion resistance and optimize the heat-treatment process of AISI 439 ferrite stainless steel silicon and tin alloys with reduced chromium. The microstructure of the specimens and deposition under each condition were analyzed. The production of oxide films was compared based on the thickness..... More

Korean J. Met. Mater. 2018;56(9):652-657.   Published online 2018 Sep 5
DOI: https://doi.org/10.3365/KJMM.2018.56.9.652

Abstract
In this work, the growth of nanotubular oxide layers on Ti1-xNix (x=0.49, 0.498, 0.511, 0.522, 0.525) shape memory alloys was investigated. All of the Ti-Ni alloys were fabricated by arc melting process under high vacuum atmosphere. The crystal structure and the growth of the nanotubular oxide layers were investigated by..... More

조영욱, 원종호, 우정호, 유상호, 조영래
Korean J. Met. Mater. 2018;56(4):289-295.   Published online 2018 Apr 5
DOI: https://doi.org/10.3365/KJMM.2018.56.4.289

Abstract
Oxi-nitrocarburizing treatment was performed to improve the anti-corrosion and anti-wear properties of low carbon steels. The oxi-nitrocarburizing was carried out in 2 steps: a gas nitrocarburizing step at 560 ℃ and an oxidation step at 550 ℃ for 30 min with steamed water. The mechanical and chemical properties of the..... More
