Abstract
The primary boundary of the CANDU reactor consists of Zr-2.5%Nb alloy pressure tubes and SA106 alloy feeder pipes. The pressure tubes are exposed to fast neutron (E>1Mev) irradiation during reactor operation, and experience dimensional changes. The actual dimensional change in the pressure tube during in-service operation is greater than the..... More

                        
Susceptibility to Severe PWSCC (primary water stress corrosion cracking) of LTMA (low temperature mill anneal) Alloy 600

Korean J. Met. Mater. 2020;58(12):815-821.   Published online 2020 Dec 4
DOI: https://doi.org/10.3365/KJMM.2020.58.12.815

Abstract
It has been proposed that a primary water stress corrosion cracking (PWSCC) in pressurized water reactor (PWR) is governed by a lattice contraction due to a short range ordering reaction in Alloy 600. This leads researcher to think that the kinetics of lattice contraction may control a susceptibility of PWSCC..... More

Visualization of Magnetic Domains in Electrical Steel Using High-Resolution Dark-Field Imaging
Youngju Kim, Jongyul Kim, Daniel Seth Hussey, Oh Youl Kwon, Seung Wook Lee
Korean J. Met. Mater. 2019;57(6):352-359.   Published online 2019 May 16
DOI: https://doi.org/10.3365/KJMM.2019.57.6.352

Abstract
Electrical steel is a soft magnetic steel material used in electric devices such as transformers and motors. The performance of these electric devices is primarily related to the magnetic properties of electrical steel, and the assessment of the magnetic properties of electrical steel has been considered an important topic. We..... More
