PROFESSIONAL EXPERIENCE

Research Scientist, GE – Worked on materials problems related to steam turbines, gas turbines, jet engines and nuclear reactors — microstructure, environmental influence, fracture, fatigue, creep, life prediction, solid and liquid erosion.

Liaison Scientist, GE – Responsible for technology transfer between Corporate R & D and operating components in the power systems sector of GE Company. The components included Steam and Gas Turbine, Nuclear Energy, Transportation Systems, Power Delivery, and Construction and Engineering Services. The technologies included materials, N.D.E., environmental controls, solid mechanics, fluid mechanics, coal combustion, robotics, factory simulation, artificial intelligence, and marketing models.

Professor, Rensselaer – Taught three undergraduate and one graduate course. Design in Materials Engineering is a new undergraduate course developed to emphasize open-ended problems, and has become a successful writing – intensive course. The assigned design project in the course achieved International recognition in winning awards four years in a row.

With support from the Sloan Foundation, a new team design / research program called Student Partnerships with Industry was started. This provided a two semester six credit industry sponsored project for undergraduate teams led by graduate students.

A major new initiative in research was made possible by establishing a mechanical testing facility with the most modern equipment and skilled operating expertise. This has allowed the development of a comprehensive methodology for tensile testing of advanced materials with limited ductility.

Visiting Professor, UCSB -Taught undergraduate course in Materials Department and laboratory course in Mechanical Engineering Department.

President, MPa – Developed a life assessment methodology for gas turbine blades. This was applied initially to pumping turbines on the Alaska pipeline. A four year contract with ARCO Oil Company was used to develop and implement the procedure. An accelerated test methodology for high temperature performance optimization and design has been demonstrated for metals, polymers and ceramics. Additional contracts with EPRI, GE, Lockheed- Martin, Dow Chemical, Shell Oil, Rolls-Royce, Hitachi, ABB, Elliott and Teledyne Ryan and numerous gas turbine users have been obtained.

MAJOR SCIENTIFIC ACHIEVEMENTS

Demonstrated the connection between helium gas formation and high temperature embrittlement in irradiated austenitic steels.

Identified the key material properties influencing water droplet and cavitation erosion resistance, leading to a new erosion shield alloy.

Identified the important parameters controlling tube erosion in fluidized bed combustors, showing the link with liquid rather than solid particle erosion.

Developed a novel intercritical heat treatment to improve the toughness and resistance to temper embrittlement of steam turbine rotors.

Established a correlation between ductility and strain rate sensitivity in metallic materials which is applicable to low strain-rate creep and to high strain-rate hot workability tests.

Related cavity formation during creep to creep test parameters through density changes, showing the separate roles of each deformation parameter.

Developed a Graphical Optimization Procedure for identifying the best time / temperature parameter for extrapolation of creep rupture for any data set.

Developed a procedure for predicting creep rupture life under conditions of nonsteady temperature and stress.

Experimentally characterized the effect of temperature cycling on creep rupture of eutectic metal-matrix composites.

Measured thermal fatigue resistance of a wide range of nickel and cobalt base superalloys, and demonstrated the comparative utility for engine performance.

Experimentally characterized the grain boundary penetration of gaseous species at high temperatures in superalloys, and demonstrated this gas phase embrittlement to be the principal basis for time-dependent crack propagation in both sustained and cyclic loading.

Developed a new testing methodology for tensile creep of ceramics based on the stress relaxation test which provides an accelerated test technique to achieve very low strain rates.

Proposed a new framework for design and life assessment of high temperature engineering components. This methodology termed “Design for Performance” provides a decision support basis for repair / refurbishment of critical components.

Showed how intrinsic ductility as a function of stress and temperature can be determined from stress relaxation tests.
