Effect of the Ni plating on Al–Cu dissimilar metal laser welded joint

Autor: Hyun-Min Sung, Siwhan Lee, Dongkyu Lee, Hwangsun Kim, Sung-Gyu Kang, Gun-Do Lee, Kyeongjae Jeong, Heung Nam Han

Publikováno v: Journal of Materials Research and Technology, Vol 31, Iss , Pp 2473-2483 (2024)

In this study, the joint strength and interfacial microstructure of Al–Cu laser welded joints are investigated to understand the effect of Ni plating. Cu without plating and Cu plated with 1 μm and 4 μm of Ni were laser welded with Al, respective

Green laser powder bed fusion based fabrication and rate-dependent mechanical properties of copper lattices

Autor: Sung-Gyu Kang, Ramil Gainov, Daniel Heußen, Sören Bieler, Zhongji Sun, Kerstin Weinberg, Gerhard Dehm, Rajaprakash Ramachandramoorthy

Publikováno v: Materials & Design, Vol 231, Iss , Pp 112023- (2023)

Additive manufacturing of pure copper (Cu) via laser-powder bed fusion (L-PBF) is challenging due to the low energy absorptivity under infra-red laser. As a result, 3-dimensional architectures, known for excellent load-bearing and energy absorption c

Prediction of precipitation kinetics and strengthening in FeMnAlC lightweight steels

Autor: Jaeeun Lee, Hwangsun Kim, Kyeongjae Jeong, Seong-Jun Park, Joonoh Moon, Sung-gyu Kang, Heung Nam Han

Publikováno v: Journal of Materials Research and Technology, Vol 14, Iss , Pp 2897-2908 (2021)

Fe–Al–Mn–C steels have superior mechanical properties, such as high yield and tensile strengths and low density, which make them suitable for applications in the automotive and defense industries. In particular, the aging of these steels at cer

Exploiting elastic buckling of high-strength gold nanowire toward stable electrical probing

Autor: Jong-Hyun Seo, Sung-Gyu Kang, Yigil Cho, Harold S. Park, Youngdong Yoo, Bongsoo Kim, In-Suk Choi, Jae-Pyoung Ahn

Publikováno v: iScience, Vol 25, Iss 10, Pp 105199- (2022)

Summary: Buckling is a loss of structural stability. It occurs in long slender structures or thin plate structures which is subjected to compressive forces. For the structural materials, such a sudden change in shape has been considered to be avoided

Selective crack suppression during deformation in metal films on polymer substrates using electron beam irradiation

Autor: So-Yeon Lee, Kyung Ryoul Park, Sung-gyu Kang, Ji-Hoon Lee, Eun-chae Jeon, Cheol-Hwee Shim, Jae-Pyoung Ahn, Dong-Ik Kim, Heung Nam Han, Young-Chang Joo, Changsoon Kim, In-Suk Choi

Publikováno v: Nature Communications, Vol 10, Iss 1, Pp 1-8 (2019)

Cracking in thin films is usually associated with failure. Here, the authors use an electron beam to selectively irradiate a copper thin film on a polymer substrate and introduce designed cracks under tension to make a strain responsive organic light
