Thermal Conductivity of Double-Layer Clad Metals along the Thickness Direction Using Light Flash Analysis and Estimation Models
2층금속 클래드메탈의 두께방향으로 섬광법 적용 열전도도 측정과 예측모델 연구
Jong-Gu Kim, Jae-Hoon Ju, Dong-Yong Kim, Sung Hyuk Park, Young-Rae Cho
김종구, 주재훈, 김동용, 박성혁, 조영래
Korean J. Met. Mater. 2017;55(7):523-528.   Published online 2017 Jul 4
DOI: https://doi.org/10.3365/KJMM.2017.55.7.523

Heat transfer plays a critical role in the fabrication of high efficiency electronic devices. Double-layer clad metals consisting of stainless steel (STS) and aluminum (Al) alloy were fabricated by the roll bonding process, and their thermal conductivity was calculated using measurements of density, specific heat, and thermal diffusivity obtained by.....

Korean J. Met. Mater. 2017;55(6):446-452.   Published online 2017 Jun 1
DOI: https://doi.org/10.3365/KJMM.2017.55.6.446

The thermal properties of two-layered materials composed of a polymer layer embedded with dielectric AlN particles (AlN composite) coated on top of an aluminum (Al) substrate were investigated by light flash analysis (LFA). The thermal conductivity of the specimens was measured as a function of the AlN composite volume fraction..... More
