Dong Yang Defends PhD Thesis

CMCRL Student Dong Yang successfully defended his PhD dissertation this morning, "Factors Affecting Boiler Tube SAC"

Congratulations!

ASM Poster Session

The CMCRL's own Ananya Bhattacharya was awarded one of two graduate awards in the ASM student poster session last week. The topic of the poster was "Stress Corrosion Cracking of Duplex Stainless Steels in Sulfide-Containing Caustic Solutions".

There were at least six graduate posters in the running; congratulations, Ananya!

CORROSION 2008

Georgia Tech's corrosion group, led by NACE Fellowship award reciever Dr. Preet Singh, presented three technical papers during the conference. Three first year PhD students won awards for Georgia Tech including the annual NACE Race, and student "team jeopardy" competition.

Conference papers:

  • Taylor, Matthew, "Hydrogen Permeation of Alloy 22" abstract

  • Bhattacharya, Ananya, "Corrosion of Duplex Stainless Steels in High pH Caustic Solution"abstract

  • Asher, Stefanie, "Hydrogen Production and Permeation of X-65 Pipeline Steel in Near Neutral pH Environments"abstract

  • Dong Yang, "Role of Carbon Steel Microstructure on SAC of Boiler Tubes"abstract



Awards

  • Dr. Preet Singh: NACE Fellowship Award

  • Lindsey Goodman: NACE Race 2008: First Place, Women's Division

  • Kevin Chasse: NACE Race 2008: Third Place, Men's Division

  • Chasse, Goodman and Taylor: Nace Student Jeopardy Team Champions, 2008

Graphical Sketching

CMCRL student Matthew Taylor entered three thermodynamics related graphs into a short contest from the makers of the scientific sketching software "Graph Sketcher". A sketch of the Pourbaix Diagram for Iron was selected as the overall winner of the contest and will be published on the graph sketcher website shortly.


The winning entry. Note: this is a textbook-style sketch and not 100% accurate



The Pourbaix Diagram is an important thermodynamic map in pH-potential space, which is used by corrosion engineers to predict the stable species (ions, metal, oxides, etc.) for a given pH (acidity/alkalinity) and electrochemical potential (voltage).

Graduate Student Recruitment

New graduate student recruitment was last week. Attached is the poster we used to communicate our group's mission and research.
