QuesTek's Dave Snyder will be giving a presentation at the 2017 Additive Manufacturing with Powder Metallurgy Conference:

1. ICME-based Design of New High-Performance Alloys for Additive Manufacturing

Authors: David Snyder (presenter, Senior Materials Engineer), Dr. Greg Olson, Dr. Jason Sebastian, Dave Snyder

Abstract: 

Integrated Computational Materials Engineering (ICME) methodologies and tools have been developed and applied to the additive manufacturing (AM) of metals to optimize both feedstock and process conditions for improved performance and reliability. The development of a new class of precipitation hardenable aluminum alloys optimized for use in laser powder bed fusion (LPBF) systems will be discussed. Limitations in the AM processing of high-strength aluminum will be outlined, as well as the development and application of selected ICME models to address these in new aluminum alloy design. Concept feasibility is demonstrated using bead-on-plate welding trials in a LPBF system. Down-selected and refined alloy designs have been produced at commercially-relevant scales via inert gas atomization, and evaluated in commercial LPBF systems for processing and post-process response. The results of these evaluations and the demonstrated mechanical properties of the new materials will be presented.
