Advanced Engineering Materials, EarlyView.This study explored how effective nickel aluminide coatings are obtained in providing oxidation resistance applied to the Inconel 738 alloy, modeling with diffusion models. In the present study, kinetics and thermal behavior of the Inconel 738 alloy were studied by the low‐temperature thermoreactive aluminizing process, which was carried out at 625°C ...

Oxidation kinetics of a Ni-Cu based cermet at high temperature [PDF]
, 2013 The oxidation kinetics of a cermet composed of Ni–Cu alloy and nickel ferrite was studied by thermogravimetry at 960 °C under oxygen in the range 0.5–77 kPa. After an initial mass increase up to 15 g/m2 due to oxidation of surface metallic particles, the

Advanced Engineering Materials, EarlyView.Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Development of Cu CMP process for Cu-to-Cu wafer stacking
Journal of the Microelectronics and Packaging Society, 2013 웨이퍼 적층 기술은 반도체 전·후 공정을 이용한 효과적인 방법으로 향후 3D 적층 시스템의 주도적인 발전방향이라고 할 수 있다. 웨이퍼 레벨 3D 적층 시스템을 제조하기 위해서는 TSV (Through Si Via), 웨이퍼 본딩, 그리고웨이퍼 thinning의 단위공정 개발 및 웨이퍼 warpage,열적 기계적 신뢰성, 전력전달, 등 시스템적인 요소에 대한 연구개발이 동시에 진행되어야 한다. 본 연구에서는 웨이퍼 본딩에 가장 중요한 역할을 하는 Cu CMP (chemical mechanicalpolishing) 공정에 대한 특성 분석을 진행하였다.
