| Abstract Scope |
The ill-conceived “service economy” that ravaged domestic manufacturing for 3 decades largely took American metallurgy with it. Meanwhile, with Peter Voorhees playing a central role, a metallurgy faculty refugee camp assembled at Northwestern University not only preserved the discipline but established it in a new form defining the frontier of materials design. Two generations of Voorhees coarsening models for nondilute multicomponent systems have contributed to a highly efficient parametric approach to alloy design. A Voorhees algorithm defined the core structure of the PrecipiCalc mean-field precipitation simulator central to the success of the historic DARP-AIM program enabling accelerated materials qualification. The NIST-supported CHiMaD design center co-directed by Voorhees demonstrated the generality of CALPHAD-based design across materials classes including thermoelectric semiconductors and polymers. Most recently, efforts in alloy design for additive manufacturing have delivered a predictive theory for the columnar-to-equiaxed transition in grain structures, integrated with dynamic simulation of inoculant evolution. |
