Abstract
Funds are provided to support collaborative research with industry on the three-dimensional characterization of microstructures, residual stress measurement, and macro-scale mechanical properties characterization.The research team includes the world s leading producer of structural aluminum alloys, Alcoa, and one of two high energy x-ray sources in the U.S., the Cornell High Energy Synchrotron Source (CHESS). Within CHESS the Integrated Simulation and x-ray Interrogation Tools and training for micro-mechanics center (InSitu), which focuses specifically on enabling industrial x-ray users, will be intimately involved. The high energy, high flux beams of x-rays at CHESS can penetrate centimeters of aluminum; crystals deep within a typical aluminum work-piece can be characterized in minutes or even seconds. To forge a connection with design practice, sophisticated signal processing algorithms will be used and connections will be made to the measured fields of orientation, strain and defect density to conventional fracture mechanics parameters such as the stress intensity factor (K) and J. In this way the use of these cutting edge experimental methods will be accelerated producing a unique class of 3D, time resolved characterization data then applying it to the most critical design challenges faced by Alcoa using novel state-of-the-art "big data" methods.
