Design, Development, and Qualification of Computationally Designed Alloys

QuesTek Innovations LLC has applied its Materials by Design® computational design technology and its Integrated Computational Materials Engineering (ICME)-based methods to successfully design, develop and implement two new high-performance gear steels (Ferrium® C61™ and Ferrium C64® steels) and two new high-performance structural steels (Ferrium S53® and Ferrium M54® steels) that are commercially available from Carpenter Technology. All four Ferrium alloys have been approved for use in demanding flight critical rotorcraft applications and have been awarded SAE AMS numbers for procurement. QuesTek has also designed several other high performance alloys using ICME technologies, including a stainless nitridable bearing and gear steel, a new high strength/high SCC-resistant aluminum alloys (upgrade from 7050 and 7075 aluminum), a beryllium-free Cu-Ni alloy, a castable titanium alloy, and a high strength/high toughness castable stainless steel.
