We continue to advance the technical forefront of computational material design tools, working independently and with highly-regarded colleagues in industry, government and academia. Our leadership in computational material design technology helps us put some of the richest material design insights into practical application.
Technology Development Leadership
QuesTek has been recognized since its inception as a global leader in computational materials design technology and its practical application. Working closely with colleagues in industry, government and academia, we continue to advance the forefront of computational material science technology (and underlying theory) and its practical real-world application of Materials by Design® as illustrated in the representative projects described below.
Digital 3-D Structure Consortium funded by DARPA and ONR
We’re leading a team of researchers working on the Digital 3-D Structure Consortium, a $5.7 million, 5-year-long program funded by the U.S. Defense Advanced Research Projects Agency (DARPA) and the Office of Naval Research (ONR). The team consists of: QuesTek as program leader; Colorado School of Mines; Georgia Institute of Technology; Massachusetts Institute of Technology; Northwestern University; Scientific Forming Technologies Corp.; and the University of Michigan. The program is integrating a suite of multi-scale tomographic microstructural characterization tools with higher-fidelity 3D microstructural simulation tools in order to enable greater accuracy in accelerated materials design and development.
Microstructure Modeling funded by NASA
During 2006-2009 we completed a NASA-funded project entitled “Microstructure Modeling of 3rd Generation Disk Alloys”. The program modeled, validated and predicted precipitation microstructure evolution using PrecipiCalc® software for 3rd generation Ni-based gas turbine disc superalloys during processing and service, with a set of logical and consistent experiments and characterizations.
Fatigue Modeling funded by the U.S. Air Force
During 2009 we completed a U.S. Air Force-funded SBIR project entitled “3D Tomography-Assisted Mechanistic Fatigue Modeling and Life Prediction for Dual Microstructure Heat Treated Aeroturbine Disks”. QuesTek partnered with Prof. David McDowell of the Georgia Institute of Technology and a leading OEM in order to demonstrate the feasibility of a microstructure-sensitive fatigue modeling framework for the prediction of location specific lifing for Dual Microstructure Heat Treatment (DMHT) aeroturbine disk components.
Machining Modeling funded by NIST
We’re part of a team that is investigating “Integrated Multiscale Modeling for Development of Machinable Advanced Alloys and Corresponding Component Machining Processes,” in a 3-year-long (2010-2012), approximately $3.2 million Technology Innovation Program (TIP) funded by the National Institute of Science and Technology (NIST). The program is being led by Third Wave Systems of Minneapolis, MN, and will enable the production of highly machinable, advanced alloys through the coupling of micromechanical models with physics-based machining models.
