RESEARCH EXPERIENCE

Texas A&M University, 2007- Present

Fabrication, characterization and testing of Nb sheets for forming applications:

Development of texture variations in sheet material by thermo-mechanical processing.

Mechanical testing of sheet anisotropy using tensile tests,

Microtexture characterization using OIM analysis.

Microstructure refinement of bulk Nb for superconducting wire applications:

(collaboration with Oxford Instruments Superconducting Technologies):

Microstructure development to achieve better co-deformation characteristics of pure Nb.

Analyzed co-deformation characteristics of a Cu-Nb composite conductor in proof of concept experiments.

This process is currently being pursued by Oxford Instruments for their Nb -Sn conductor development

program.

Seamless Nb tube for SRF cavities: Development of seamless Nb tube through a innovative shear

deformation process for hydroforming applications. Involved in the production of tube by area reduction

extrusion, and shear processing. Performed mechanical testing along the different direction s to evaluate

formability, and related the properties to XRD macro texture.

Predictions of bi-crystal deformation behavior in Nb: Developed a crystal plasticity/phase field model to

predict the stress strain response of a crystalline material under different loading conditions. Development of

code using MATLAB for viscoplasticity, texture representation, and prediction of orientation data.

National High Field Magnet Lab, Tallahassee, FL, July 2012

Investigation of bi-crystal deformation behavior in Nb

Conducted advanced microstructural characterization involving high resolution EBSD, to evaluate deformation

characteristics of a Nb bi-crystal.

Analyze and Interpret Data for Experiment design and publications.
