Abstract
Modern military and civilian aircraft technologies are pushing the performance envelope through design and use of new advanced materials with superior property combinations. Aircraft powerplant manufacturers are facing intense competition to efficiently deliver ever increasing thrust, while meeting the highest standards of reliability and performance over an expanded service life. These performance criteria often impose stringent requirements on the microstructure of the material used in the manufacture of the turbine engines. Titanium alloys are used extensively in turbine engines due to their unique combination of excellent mechanical and physical properties. Design of the turbine engine components for optimal performance under strenuous operating conditions is greatly complicated by the lack of material models that reliably link microstructure and properties. Therefore, MRL/Drexel team offers a next-generation approach to cost-effective accelerated insertion of high strength, high temperature titanium alloys in modern turbine engines by developing and validating a reliable multi-scale physics-based modeling framework that employs an objective and comprehensive quantification of the microstructure using n-point correlation functions. The proposed development will be undertaken in close collaboration with equipment manufacturers and primary titanium producers. The collaboration is expected to result in major building blocks for the Integrated Computational Materials Engineering (ICME) infrastructure. BENEFIT: multi-scale models that link higher-order microstructure descriptions to anisotropic mechanical properties of alpha/beta titanium alloys using a informatics-based approach.
