GE Schenectady Cores and Castings (SCC) leading the casting of nickel-based superalloy single crystal turbine blades and other cast parts for large industrial-based gas turbines (IGT's).

I am a research engineer at GE and deal with the behavior of metals during thermomechanical processing. GE makes many things by processing metal—some are very critical to peoples' safety—e.g. the rapidly rotating parts in the jet engines of a passenger airplane—and some mostly just have to look nice—e.g. a refrigerator or dishwasher door or cooktop appliance. Processing steps have a big influence on properties and mechanical performance of finished products in part because the state of the underlying microstructure can undergo significant evolution during forming. Strides in understanding are being made by rooting material behavior to phenomena occurring at the micro scale.I have interest in all aspects of metals processing including computational modeling and mechanics which draws upon a variety of disciplines from many fields of study including continuum mechanics, inelasticity, polycrystal plasticity, finite element modeling, parallel and high performance computing. Materials of interest include titanium alloys and intermetallics (Ti6-4, TiAl), nickel-based superalloys (R88, R104, R95, R706, R718).Patents:Die and Method for Reducing or Controlling the Formation of Flash on Parts, US Patent 6,370,933.Airfoil qualification system and method, Mika, Karafillis, US Patent 6,969,821.Method for determining and compensating for peening-induced distortion, US Patent 7,065,479 B2.Hybrid metal forming system, US 7,162,910.System and method for tube bending, US 7,231,798Hybrid metal forming system, US 7,240,532Thermal Forming, US 7,412,300Deposition friction stir welding process and assembly, US 7,455,212
