The Balk research group applies a variety of characterization and testing techniques to investigate the structure and mechanical behavior of materials. In particular, the group focuses on three groups of materials:
- Thin film and bulk nanoporous metals and alloys are fabricated by dealloying precursor materials, which have been made via magnetron sputtering or arc melting. Links between the structure and mechanical/chemical properties of these materials are studied.
- Dispenser cathodes are a significant focus of our research efforts, especially scandate cathodes. Kelvin probe measurements, electron microscopy, and x-ray photoelectron spectroscopy are employed to investigate material properties and link these to the cathode’s emission characteristics.
- High entropy alloys are fabricated and studied both in bulk and thin film forms, to investigate structure-property links in mechanical behavior.
