A New Fracture Analysis Technique for Charpy Impact Test Using Image Processing
Tae Chang Park, Beom Suk Kim, Ji Hee Son, Yeong Koo Yeo
Korean J. Met. Mater. 2021;59(1):61-66.   Published online 2021 Jan 5
DOI: https://doi.org/10.3365/KJMM.2021.59.1.61

Abstract
The Charpy impact test is used to identify the transition between ductility and brittleness. The percentages of ductile and brittle fractures in steel can be evaluated based on each fracture area, which is presently determined by an analyzer with the naked eye. This method may lead to subjective judgement, and..... More

Comparative Study of Estimation Methods of the Endpoint Temperature in Basic Oxygen Furnace Steelmaking Process with Selection of Input Parameters
Tae Chang Park, Beom Seok Kim, Tae Young Kim, Il Bong Jin, Yeong Koo Yeo
Korean J. Met. Mater. 2018;56(11):813-821.   Published online 2018 Nov 5
DOI: https://doi.org/10.3365/KJMM.2018.56.11.813

Abstract
The basic oxygen furnace (BOF) steelmaking process in the steel industry is highly complicated, and subject to variations in raw material composition. During the BOF steelmaking process, it is essential to maintain the carbon content and the endpoint temperature at their set points in the liquid steel. This paper presents..... More
