1. Ferrium M54 - ICME Development from Genome to Flight
Authors: Jason Sebastian, Greg Olson
QuesTek Innovations, a leader in the field of Integrated Computational Materials Engineering (ICME), will present a “success story” overview of the development of their new ultra-high strength, high performance structural steel, Ferrium M54. The development of this alloy was sponsored under a U.S. Navy-funded Small Business Innovation Research (SBIR) program with the goal of developing a cost competitive, drop-in replacement for AerMet®100 aerospace alloy. A variety of ICME- and “Accelerated Insertion of Materials (AIM)”-type computational models were employed during the design and development of M54, and highlights will be presented. M54’s overall development progressed from a clean sheet design in 2007 to a precise chemical composition in less than one year, and the first 10-ton VIM/VAR ingot was produced the following year. An Aerospace Material Specification (AMS 6516) was issued two years later, and inclusion in the MMPDS handbook for A- and B- basis design minima was approved in December 2013. QuesTek coordinated the production and qualification of hook shank components made from M54 that were successfully flight tested in December 2014. Highlights will be presented from a recent (August 2016) National Institute of Standards and Technology-funded case study (carried out by Nexight Group and Energetics Incorporated) detailing overall timeline of the successful development of M54 and its application to U.S. Navy hook shanks. Results and data for M54 will be presented from throughout the alloy development process, with a focus on the properties that distinguish it from legacy materials. Highlights of recent M54 application and commercialization activities will also be presented.
2. Improving Manufacturing Quality Using Integrated Computational Materials Engineering

The prediction of materials properties and their variation within a specification or design space is key in ensuring reliable production uniformity. To capture the complex mechanisms that underpin materials’ performance, processing-structure-properties links are established using a “systems design” approach. QuesTek Innovations LLC has previously utilized multi-scale ICME modeling methodologies and tools (e.g., CALPHAD thermodynamic and kinetic databases, property models, etc.) and advanced characterization techniques to design advanced materials with improved performance. This work focuses on building an ICME infrastructure to predictively model properties of critical materials for energy and defense applications by optimizing existing materials, performing calculations to quantify uncertainty in material properties, and defining target specification ranges and processing parameters necessary to ensure design allowables. Focusing on two material case studies, 304L austenitic stainless steel and glass-ceramic-to-metal seals, we show how these ICME techniques can be used to better understand process-structure and structure-property relationships. These efforts provide pathways to novel, fully optimized alloys and production processes using the Accelerated Insertion of Materials (AIM) methodology within ICME. The AIM method is used for probabilistic properties forecasting to enable rapid and cost-efficient process optimization and material qualification.
