Diagnosis of Mechanoluminescent Crack Based on Double Deep Learning in Al 7075
이중 인공지능을 이용한 Al 7075 합금에서의 압광 균열 진단 연구

Received 2023 Aug 31     Accepted 2023 Oct 21     Published online 2023 Nov 30
DOI: https://doi.org/10.3365/KJMM.2023.61.12.958    
[Epub ahead of print]
The phenomenon of mechanoluminescence (ML) refers to the emission of light induced by mechanical stimulation applied to mechano-optical materials for example SrAl2O3:Eu,Dy (SAO). Numerous technologies on the basis of ML have been presented to visualize the stress or strain in various structures for the applications including structural health monitoring. As a result, extensive... More
Effect of High Temperature Oxidation on Surface Pit and Recrystallization of Directionally Solidified CM247LC Superalloy in Creep Gauge
일방향 응고 CM247LC 초내열합금 크리프 시편 게이지에서 고온 산화가 표면 피트 및 재결정 형성에 미치는 영향

Received 2023 Nov 3     Accepted 2023 Nov 5     Published online 2023 Nov 30
DOI: https://doi.org/10.3365/KJMM.2023.61.12.951    
[Epub ahead of print]
This study analyzed a recrystallization phenomenon that occurred simultaneously with hightemperature oxidation on the surface of a directionally solidified CM247LC creep specimen, using optical and scanning electron microscopy. After heat treatment, the surface of the specimen subjected to the creep test at 982oC was oxidized by exposure to high temperature and underwent microstructural... More
Effect of Corrosive Environment on Friction Characteristics of Brake Friction Materials
브레이크 마찰재의 마찰특성에 미치는 부식 환경의 영향

Received 2023 Sep 7     Accepted 2023 Oct 10     Published online 2023 Nov 30
DOI: https://doi.org/10.3365/KJMM.2023.61.12.943    
[Epub ahead of print]
The friction properties of brake friction materials are investigated utilizing the different car cleaners. Water, wheel cleaner and tire dressing were used to designate driving conditions in the field. The friction materials were soaked in each solution before friction test. The Coefficient of friction (COF) was similar in the case of water and... More
Tensile and Fatigue Properties of WC-20 wt%Co Cemented Carbides under Microstructural Variations
WC-20wt%Co 초경 합금의 미세 조직 변화에 따른 인장 및 피로 성질

Received 2023 Jul 28     Accepted 2023 Sep 5     Published online 2023 Nov 30
DOI: https://doi.org/10.3365/KJMM.2023.61.12.933    
[Epub ahead of print]
WC-Co cemented carbide has excellent mechanical properties and is widely used in many industrial applications including cold forging dies and cutting tools. The tensile and fatigue properties of WC-20wt%Co cemented carbides with microstructural variations were investigated. Microstructure parameters such as Co binder content, WC particle size, binder mean free path, and contiguity were... More
