Journal ArticleDOI
Dissimilar laser welding of a CoCrFeMnNi high entropy alloy to 316 stainless steel
João Pedro Oliveira,Corinne Hubinont,Jiajia Shen,Zhi Zeng,Jeong Min Park,Yeon Taek Choi,N. Schell,Emad Maawad,Norman Y. Zhou,Hyoung Seop Kim +9 more
TL;DR: In this article, the microstructure evolution across the welded joints was assessed and rationalized by coupling electron microscopy, high energy synchrotron X-ray diffraction, mechanical property evaluation, and thermodynamic calculations.
Journal ArticleDOI
Steel-copper functionally graded material produced by twin-wire and arc additive manufacturing
Corinne Hubinont,Tiago A. Rodrigues,N. Bairrão,Francisco Werley Cipriano Farias,A. Shamsolhodaei,Jiajia Shen,N. Zhou,Emad Maawad,Norbert Schell,Telmo G. Santos,João Pedro Oliveira +10 more
TL;DR: In this article, a functionally graded material (FGM) part was fabricated by depositing a Cu-based alloy on top of a high strength low alloy (HSLA) steel by twin-wire and arc additive manufacturing (TWAAM).
Journal ArticleDOI
Improving the ductility in laser welded joints of CoCrFeMnNi high entropy alloy to 316 stainless steel
Jp Oliveira,A. Shamsolhodaei,Jiajia Shen,João G. Lopes,M. Gonçalves,Mariana de Brito Ferraz,Lourenço Piçarra,Zhipeng Zeng,Norbert Schell,Ning Zhou,Hyoung Seop Kim +10 more
TL;DR: In this paper , the microstructure evolution across the welded joint is assessed and correlated to its mechanical performance using electron microscopy, high energy synchrotron X-ray diffraction and mechanical testing aided by digital image correlation.
Journal ArticleDOI
Laser welding of H-phase strengthened Ni-rich NiTi-20Zr high temperature shape memory alloy
João Pedro Oliveira,Jiajia Shen,J.D. Escobar,Camilo A.F. Salvador,Norbert Schell,N. Zhou,Othmane Benafan +6 more
TL;DR: In this article, a Ni-rich NiTi-20Zr (at.%) high temperature shape memory alloy was used for laser welding and defect-free welds were obtained with a conduction welding mode.
Journal ArticleDOI
Microstructure and mechanical properties of gas metal arc welded CoCrFeMnNi joints using a 308 stainless steel filler metal
Jiajia Shen,Rita Gonçalves,Yeon Taek Choi,João G. Lopes,J. Yang,Norbert Schell,Hyoung Seop Kim,Jp Oliveira +7 more
TL;DR: In this article , gas metal arc welding of a CoCrFeMnNi high entropy alloy was performed using 308 stainless steel filler wire, and the microstructure evolution and mechanical properties of the welded joints were investigated.
