Journal ArticleDOI
Microstructure and mechanical properties of Al-Mg-Zr alloys processed by selective laser melting
Joseph R. Croteau,Seth Griffiths,Marta D. Rossell,Christian Leinenbach,Christoph Kenel,Vincent Jansen,David N. Seidman,David C. Dunand,Nhon Q. Vo +8 more
TL;DR: In this paper, gas-atomized powders of two ternary alloys, Al-3.60Mg-1.18Zr and Al 3.57Zr, were densified via laser powder bed fusion.
Journal ArticleDOI
Acoustic emission for in situ quality monitoring in additive manufacturing using spectral convolutional neural networks
TL;DR: In this paper, the authors investigated the feasibility of using acoustic emission for quality monitoring and combined a sensitive acoustic emission sensor with machine learning, where the acoustic signals were recorded using a fiber Bragg grating sensor during the powder bed additive manufacturing process in a commercially available selective laser melting machine.
Journal ArticleDOI
3D Laser Shock Peening – A new method for the 3D control of residual stresses in Selective Laser Melting
Nikola Kalentics,Eric Boillat,Patrice Peyre,Cyril Gorny,Christoph Kenel,Christian Leinenbach,Jamasp Jhabvala,Roland E. Logé +7 more
TL;DR: In this article, a hybrid additive manufacturing process based on the integration of Laser Shock Peening (LSP) with selective laser melting (SLM) is described. But the authors do not consider the effect of residual stresses in the as-built (AB) state of SLM parts in the subsurface region.
Journal ArticleDOI
Deep Learning for In Situ and Real-Time Quality Monitoring in Additive Manufacturing Using Acoustic Emission
TL;DR: This paper is a supplement to existing studies in this field and proposes a unique combination of highly sensitive acoustic sensor and machine learning for process monitoring of AM processes since it requires minimum modifications of commercially available industrial machines.
Journal ArticleDOI
In situ investigation of phase transformations in Ti-6Al-4V under additive manufacturing conditions combining laser melting and high-speed micro-X-ray diffraction
Christoph Kenel,Christoph Kenel,Daniel Grolimund,Xiao Li,Ezequiel Panepucci,V.A. Samson,D. Ferreira Sanchez,Federica Marone,Christian Leinenbach +8 more
TL;DR: In this paper, the phase evolution of Ti-6Al-4V was observed in real-time by combining in situ X-ray diffraction and high-speed imaging to monitor phase evolution upon cyclic rapid laser heating and cooling.
