Abstract

Materials development is often slow and costly, and out of sync with the rest of engineering, where design is aided by computer models and analysis. Integrated Computational Materials Engineering (ICME) processes are emerging as effective tools to reconfigure materials development and accelerate implementation of new alloys into real-world applications. In each project, proprietary thermodynamic and kinetic databases that feed into precipitation prediction and microstructural evolution models are used to adjust chemistry and thermal processing parameters in order to predict equilibrium phases and ensuing properties. These models are further fine-tuned over time through experimentation. Ferrium steels are stronger, tougher, more corrosion resistant, more temperature resistant, and have other improvements compared to traditional aerospace steels such as 4340, 300M, 9310, and maraging grades. ICME can be applied in true engineered products, resulting in exceptional performance.
