    Dear All,

    We hope that everyone is coping with the pandemic well and we hope to continue to bring meaningful content and connections as best we can during these trying times. Both Michael (ASM Pittsburgh - Chair) and Corinne (ASM Pittsburgh - Vice Chair) have put together another excellent virtual meeting for November focusing on modeling and additive manufacturing of metals.  Both Professor Rollett and Dr Payton have interesting talks and both are excellent speakers, so this should be a great event! 

    The meeting will be this Thursday, November 19th starting at 7:00 pm with login starting at 6:45 pm. If you have any difficulty in logging in, please go through attached "How to use Ringcentral meetings" file and follow the steps accordingly.

     

    Dr Eric Payton

     

    Title: "A Vision of the Future Role of Modeling & Simulation in Aerospace Metals Processing."

    Abstract:
    Microstructures retain a "memory" of prior processing history through the size, shape, orientation, and spatial distributions of phases and defects. A complex interplay exists between grain size distribution, heterogeneity of stored strain, and joint size-spatial distributions of secondary phases. This is reflected in the time evolution of the grain size distribution upon thermal exposure. This talk will present a vision for the future roles of modeling and simulation in aerospace alloy development and processing, including the roles of machine learning and data science. The driving forces behind this vision will be discussed, along with strengths and limitations of current modeling and simulation capabilities with respect to enabling prediction of microstructure variation across aerospace components and the optimization of performance in service.

    Bio:
    Dr. Eric Payton serves as the Research Leader for the Metallic Materials and Processing Team at the Air Force Research Laboratory Materials and Manufacturing Directorate. His research focuses on the development of novel techniques for characterization and modeling of materials microstructure evolution during thermomechanical processing of metallic materials. Prior to his transition to government service in 2015, he was a member of the faculty at the New York State College of Ceramics at Alfred University, held post-doctoral positions at Ruhr University in Bochum, Germany, and the Federal Institute for Materials Research and Testing in Berlin, Germany, and obtained a PhD in Materials Science and Engineering from Ohio State.  

     

     

    Dr. Anthony Rollett

    An Update on Metals 3D Printing aka Additive Manufacturing

     

    Abstract: Brief update on 3D printing of metals.  I will cover current examples of parts being printed, evolution of the printers, efforts to develop qualification and certification procedures, synchrotron visualization of laser melting, modeling of microstructure evolution in AM, phase transformation during rapid cooling, alloys being used, machine learning and high temperature heat exchangers.

     

    Bio: Rollett's research focuses on microstructural evolution and microstructure-property relationships in 3D. Interests include 3D printing of metals, materials for energy conversion systems, strength of materials, constitutive relations, microstructure, texture, anisotropy, grain growth, recrystallization, formability, extreme value statistics and stereology. Important recent results include development of a spectral approach to eigenstrain problems, validation of the 3D elasto-viscoplastic FFT code against synchrotron x-ray diffraction data, definition of process windows in 3D printing through characterization of porosity, prediction of solidification microstructure, the appearance of new grains during grain growth, and grain size stabilization.  He is the U.S. Steel Professor of Metallurgical Engineering and Materials Science in the Materials Science & Engineering department at Carnegie Mellon University and before 1995 was with the Los Alamos National Laboratory. He is a Fellow of several professional societies and will be the International Francqui Professor for 2020-2021, from the Francqui Foundation, Belgium. He is the co-Director of CMU's NextManufacturing Center which is dedicated to advancing manufacturing especially through 3D metals printing.  He has over 250 peer-reviewed publications.
