DOI: https://doi.org/10.3365/KJMM.2023.61.4.301

Abstract
The creep properties of Alloy 690, used as a steam generator tube material in nuclear power plants, were evaluated at 650°C, 750°C, and 850°C. The parameters of creep life prediction models were derived using the Larson-Miller (LM), Manson-Haferd (MH), and Orr-Sherby-Dorn (OSD) models, to use as mechanical properties under a..... More

Korean J. Met. Mater. 2020;58(9):617-625. Published online 2020 Aug 13
DOI: https://doi.org/10.3365/KJMM.2020.58.9.617

Abstract
The vacuum carburizing behavior of AISI 4115 steel according to acetylene flow rates (1, 5, 10, 20, 30, 40, and 50 sccm) and temperatures (900, 950, and 1000 ^oC) was quantitatively investigated through microstructure, carbon concentration and hardness analyses. As the acetylene flow rate increased, the penetration rate of carbon..... More

DOI: https://doi.org/10.3365/KJMM.2016.54.9.672

Abstract
The surface microstructure and crack formation of an aluminum die-casting mold were investigated. The mold was made of a modified STD61 steel, and was used for more than 165,000 cycles. The mold surface consisted of four layers; an oxidized layer, a decarburized layer, a network carbide layer and a tempered... More
