NSLS-II Friday Lunchtime Seminar
"The role of hard X-ray synchrotron characterization of additively manufactured metal and composite structures: enhancing processes, materials and performance"
Presented by Gary Halada, Stony Brook University, NY
Friday, November 13, 2020, 12:00 pm — ZoomGov
Focusing on current challenges in understanding the process/structure/properties/performance relationship in additively manufactured (3D printed) alloys and ceramics, this talk will outline the potential role of planned hard X-ray capabilities at NSLS II. In particular, the talk will include recent results from an ongoing study of the relationship of factors contributing to durability of laser powder bed fusion (LPDF) formed 316L stainless steel, the role of print-formed micro and nanostructural heterogeneities on surface and bulk properties, and recent X-ray studies of alloys designed for aerospace, energy infrastructure and biomedical applications. The potential for in situ and in operando studies of printing via laser melting/sintering and post-printing processing to decrease porosity, improve surface finish and mechanical properties, as well as in situ X-ray analysis during corrosion and thermomechanical testing, will enhance the value of AM for manufacturing and a wide variety of applications relevant to regional industry and commercial applications.
