Reliability is fundamental to achieve the market trust to make engineering components competitive. The typical engineering laboratory tests and qualifications are often not enough to understand the mechanics of problems arising in parts and systems during time and use. In recent years the growing connection between the two worlds of physics and engineering has helped to overcome issues that could not be solved otherwise, advancing techniques and applications. The presentation will show strategies and studies involving photovoltaic (PV) modules and additively manufactured (AM, or 3D printed) metal components. A cross-communicating top down / bottom up approach applicable to different environments has been developed to possibly merge system reliability and material analysis. Starting from PV, we know that about 24% of crystalline Silicon PV modules in an installation show cell cracks, visually detectable in the field through snail trails. X-ray Diffraction imaging has been used to visualize micro-cracks and, for the first time, stress/strain on the laminated PV cell. Another study with DuPont has used Small-Angle and Wide-Angle X-ray Scattering to understand morphology changes happening during the aging process of PV polymeric backsheet materials. The approach initially developed for PV has been recently the corner stone over which to build the metal AM strategy for Brookhaven Lab. While discussing steps of the strategy development and showing the planned way forward, we will see how BNL has been using X-ray Diffraction to visualize defects and residual stress in AM metal components: tests have been performed with GE Global Research’s samples of aviation engine turbine blades using Nickel superalloy and with Rensselaer Polytechnic Institute’s samples of CoCr and IN718 steel.
Biosketch: Dr. Alessandra Colli is the Coordinator for metal additive manufacturing at Brookhaven National Laboratory and Adjunct Professor at Stony Brook University, NY. She has a Master in Electric Engineering from the Polytechnic University of Milan, Italy, and a Ph.D. in risk and safety for energy systems from Delft University of Technology, Netherlands. She joined BNL in 2011, after working for the Joint Research Centre of the European Commission. Her expertise includes risk and reliability analysis, photovoltaic performance and degradation, energy efficiency, supervision of large-scale PV research plants and use of X-ray techniques for system reliability. She is presently guiding the metal additive manufacturing strategy development at Brookhaven Lab.
